PROFS: The Office Suite of the 1980s

Today, we take office software suites for granted. But in the 1970s, you were lucky to have a typewriter and access to a photocopier. But in the early 1980s, IBM rolled out PROFS — the Professional Office System — to try to revolutionize the office. It was an offshoot of an earlier internal system. The system would hardly qualify as an office suite today, but for the time it was very advanced.

The key component was an editor you could use to input notes and e-mail messages. PROFS also kept your calendar and could provide databases like phonebooks. There were several key features of PROFS that would make it hard to recognize as productivity software today. For one thing, IBM terminals were screen-oriented. The central computer would load a form into your terminal, which you could fill out. Then you’d press send to transmit it back to the mainframe. That makes text editing, for example, a very different proposition since you work on a screen of data at any one time. In addition, while you could coordinate calendars and send e-mail, you could only do that with certain people.
A PROFS message from your inbox
In general, PROFS connected everyone using your mainframe or, perhaps, a group of mainframes. In some cases, there might be gateways to other systems, but it wasn’t universal. However, it did have most of the major functions you’d expect from an e-mail system that was text-only, as you can see in the screenshot from a 1986 manual. PF keys, by the way, are what we would now call function keys.

The calendar was good, too. You could grant different users different access to your calendar. It was possible to just let people see when you were busy or mark events as confidential or personal.

You could actually operate PROFS using a command-line interface, and the PF keys were simply shorthand. That was a good thing, too. If you wanted to erase a file named Hackaday, for example, you had to type: ERASE Hackaday AUT$PROF.

Styles


PROFS messages were short and were essentially ephemeral chat messages. Of course, because of the block-mode terminals, you could only get messages after you sent something to the mainframe, or you were idle in a menu. A note was different. Notes were what we could call e-mail. They went into your inbox, and you could file them in “logs”, which were similar to folders.

If you wanted something with more gravitas, you could create documents. Documents could have templates and be merged with profiles to get information for a particular author. For example, a secretary might prepare a letter to print and mail using different profiles for different senders that had unique addresses, titles, and phone numbers.

Documents could be marked draft or final. You had your own personal data storage area, and there was also a shared storage. Draft documents could be automatically versioned. Documents also received unique ID numbers and were encoded with their creation date. Of course, you could also restrict certain documents to certain users or make them read-only for particular users.

More Features

Pretty good spell check options for the 1980s.
PROFS could remind you of things or calendar appointments. It could also let you look up things like phone numbers or work with other databases. The calendar could help you find times when all participants were available. PROFS could tie into DisplayWrite (at least, by version 2) so it could spell check using custom or stock dictionaries. It also looked for problematic words such as effect vs. affect and wordy phrases or clichés.

The real game changer, though, was the ability to find documents without searching through a physical filing cabinet. The amount of time spent maintaining and searching files in a typical pre-automation business was staggering.

You could ask PROFS to suggest rewrites for a certain grade level or access a thesaurus. This all sounds ordinary now, but it was a big innovation in the 1980s.

Of course, in those days, documents were likely to be printed on a computer-controlled typewriter or, perhaps, an ordinary line printer. But how could you format using text? This all hinged on IBM’s DisplayWriter word processor.

Markup


Today we use HTML or Markdown to give hints about rendering our text. PROFS and DisplayWriter wasn’t much different, although it had its own language. The 😛. tag started a paragraph. You could set off a quotation between :q. and :eq. Unnumbered lists would start with :ul., continue with :li., and end with :eul. Sounds almost familiar, right? Of course, programs like roff and WordStar had similar kinds of commands, and, truthfully, the markup is almost like strange HTML.

The Whole Office


IBM wanted to show people that this wasn’t just wordprocessing for the secretarial pool. Advanced users could customize templates and profiles. Administrators could tailor menus and add features. There were applications you could add to provide a spreadsheet capability, access different databases, and gateway to other systems like TWX or Telex.

It is hard to find any demonstrations of PROFs, but a few years ago, someone documented their adventure in trying to get PROFS running. Check out [HS Tech Channel’s] video below.

History and Future


Supposedly, the original system was built in the late 1970s in conjunction with Amoco Research. However, we’re a little suspicious of that claim. We know of at least three other companies that were very proud of “helping IBM design PROFS.” As far as we could ever tell, that was a line IBM sales fed people when they helped them design a sign-in screen with their company name on it, and that was about it.

The system would go through several releases until it morphed into OfficeVision. As PCs started to take over, OfficeVision/2 and OS/2 were the IBM answer that few wanted. Eventually, IBM would suggest using Lotus Notes or Domino and would eventually buy Lotus in 1995 to own the products.

Scandal


One place that PROFS got a lot of public attention was during the Iran-Contra affair. Oliver North and others exchanged PROFS notes about their activities and deleted them. However, deleting a note in PROFS isn’t always a true deletion. If you send a note to several people, they all have to delete it before the system may delete it. If you send a document, deleting the message only deletes the notification that the document is ready, not the document.

Investigators recovered many “deleted” e-mails from PROFS that provided key details about the case. Oddly, around the same time, IBM offered an add-on to PROFS to ensure things you wanted to delete were really gone. Maybe a coincidence. Maybe not.

On Your Own


If you want to try to build up a new PROFS system, we suggest starting with a virtual machine. If anyone suggests that wordprocessing can’t get worse than DisplayWriter, they are very wrong.

Forget Waldo. Where’s Luna 9?

Luna 9 was the first spacecraft to soft-land on the moon. In 1966, the main spacecraft ejected a 99-kg lander module that used a landing bag to survive impact. The problem is, given the technology limitations of 1966, no one is exactly sure where it is now. But it looks like that’s about to change.
A model of the Luna 9 lander with petals deployed.
We know that the lander bounced a few times and came to rest somewhere in Oceanus Procellarum, in the area of the Reiner and Marius craters. The craft deployed four stabilizing petals and sent back dramatic panoramas of the lunar surface. The Soviets were not keen to share, but Western radio astronomers noticed the pictures were in the standard Radiofax format, so the world got a glimpse of the moon, and journalists speculated that the use of a standard might have been a deliberate choice of the designers to end run against the government’s unwillingness to share data.

Several scientists have been looking for the remains of the historic mission, but with limited success. But there are a few promising theories, and the Indian Chandrayaan-2 orbiter may soon confirm which theory is correct. Interestingly, Pravda published exact landing coordinates, but given the state of the art in 1966, those coordinates are unlikely to be completely correct. The Lunar Reconnaissance Orbiter couldn’t find it at that location. The leading candidates are within 5 to 25 km of the presumed site.

The Luna series had a number of firsts, including — probably — the distinction of being the first spacecraft stolen by a foreign government. Don’t worry, though. They returned it. Since the Russians didn’t talk much about plans or failures, you can wonder what they wanted to build but didn’t. There were plenty of unbuilt dreams on the American side.

Designing a Compact RGB 14-Segment Display


The media in this post is not displayed to visitors. To view it, please log in.

Sometimes you’re looking for a component for a project that you know should exist, but you just cannot find it. Something like a 14-segment LED display, but not just one with a fixed color, instead you want some of that sweet addressable RGB-ness. Unfortunately for [EastMakes], this particular display was nowhere to be found, so he decided to try making his own.

Using addressable SK6805 RGB LEDs with a mere 1.5 x 1.5 footprint as the basis, the layout for these individual LEDs on the PCBs was determined, and a layout created in KiCad. The PCB manufacturing and assembly were straightforward enough — the thing that really makes these displays is the diffuser. Here a few different approaches were tried, including FR4 with translucent segments in the soldermask, and a 3D printed version in both white and black PLA filament.

The FR4 approach using 0.8 mm thin PCBs looked quite all right, with the addition of through vias in the 1 mm version showing how these help to boost overall brightness. The 3D printed version prototypes didn’t look too shabby either, but it would probably help a lot if this diffuser panel also fit around the LEDs to prevent light bleeding between segments.

We’d love to see this type of RGB display being experimented with, as it seems to hold a lot of promise while also definitely being something that ought to exist.

Scanning Table for the Professional Maker

Sometimes the simplest objects need some overthinking. This is exactly what [Chris Borge] realized when using his 3D scanner and finding that the included rotation table left quite a bit to be desired — providing him the perfect excuse to build a new one.

One of the main features of a rotation stage is the, well, rotation. This was done in [Chris]’s case with a NEMA 17 stepper motor, perfect for precise rotation of scanning. Hooking up the motor to a basic perf board with an Arduino Nano allows for on the fly adjustments to rotation speed. To really solidify the over-engineering, [Chris] applies his obligatory concrete mix to add some heft to the stage.

While the previous features could be removed/downgraded without much loss, the adjustable grid built into the top adds significant functionality. The grid is based on [Chris]’s past projects, which allows cross compatibility.

We love over-engineering here at Hackaday, especially when adding something new. For more prime overthought design, check out this over engineered egg cracker!

The Complex Engineering of Runways


The media in this post is not displayed to visitors. To view it, please log in.

Airport runways seem pretty simple, just another strip of asphalt or concrete not unlike the roads that our cars drive upon every day. We can even use these same highways as landing strips in a pinch, so you’d assume that the engineering for either isn’t that dissimilar. Of course, you can use a highway for an occasional emergency, but a runway that sees the largest and heaviest airplanes taxi, take off and land on a constant basis is a whole other challenge, as detailed in a recent [Practical Engineering] video and its transcript.

When you consider that an Airbus A380 the take-off weight is up to 550 ton, it’s quite clear what the challenge is for larger airports. Another major issue is that of friction, or lack thereof, as the speeds and kinetic energy behind it are so much higher. One only has to look at not only runway overruns but also when one skids off sideways due issues like hydroplaning and uneven friction. Keeping the surface of a runway as high-friction as possible and intact after hundreds of take-offs, tail-strikes and other events is no small feat.

Of course, the other part of runway engineering is for when things do go wrong and an airplane enters the runway safety areas, or overrun zones. This usually provides some flat and clear space where an airplane can safely bleed off its kinetic energy, with the collapsing surface of the EMAS technology being one of the best demonstrations of how this can be safely and dramatically shortened.

Another aspect not covered here that is part of these overrun zones are frangible structures, such as any localizer antennae of ILS, lighting, etc. Frangible here means that the structure easily collapses when a heavy airplane crashes into it without causing significant damage to the airplane.

It was the failure of such a design process that doomed the crew and passengers of Jeju Air Flight 2216 in December of 2024, when the airplane during an emergency belly landing skidded over the end of the runway. Although there was a lot of open space after the ILS localizer array with just a flimsy wall and further level fields, the ILS array’s base contained a poured concrete base on which the airplane effectively pulverized.

Making a Hidden Door Status Sensor

The door sensor in its new enclosures. (Credit: Dillan Stock)The door sensor in its new enclosures. (Credit: Dillan Stock)
A common sight in ‘smart homes’, door sensors allow you to detect whether a door is closed or open, enabling the triggering of specific events. Unfortunately, most solutions for these sensors are relatively bulky and hard to miss, making them a bit of a eyesore. This was the case for [Dillan Stock] as well, who decided that he could definitely have a smart home, yet not have warts sticking out on every single doorframe and door. There’s also a video version of the linked blog post.

These door sensors tend to be very simple devices, usually just a magnet and a reed relay, the latter signaling a status change to the wireless transmitter or transceiver. Although [Dillan] had come across recessed door sensors before, like a Z-wave-based unit from Aeotec, this was a very poorly designed product with serious reliability issues.

That’s when [Dillan] realized that he could simply take the PCB from one of the Aqara T1 door sensors that he already had and stuff them into a similar 20 mm diameter form factor as that dodgy sensor unit. Basically this just stuffs the magnet and PCB from an existing wart-style sensor into a recessed form factor, making it a very straightforward hack, that only requires printing the housings for the Aqara T1 sensor and some intimate time between the door and a drill.

Pi Pico Learns Morse Code


The media in this post is not displayed to visitors. To view it, please log in.

When [101 Things] didn’t want to copy Morse code, he decided to build a Pi Pico system to read it for him. On the face of it, this doesn’t seem particularly hard, until you look at the practical considerations. With perfectly timed dots and dashes, it would be trivial. But in real life, you get an audio signal. It has been mangled and mixed with noise and interference as it travels through the air. Then there’s the human on the other end who will rarely send at a constant speed with no errors.

Once you consider that, this becomes quite the project, indeed. The decoder captures audio via the Pi’s analog-to-digital converter. Then it resamples the input, applies an FFT, and converts the output via a complex classification pipeline that includes, among other things, Bayesian decoding. Part of the pipeline makes simple typo corrections. You can see the device do its thing in the video below.

Another issue with the code is that it decodes multiple channels in real time. So looking up spelling corrections, for example, has to be done rapidly. The device can also send code and show stats and graphics on an LCD screen.

If you know the code is arriving at a known speed, you could do something much simpler. The Pico has lots of memory which makes it easy to use complex algorithms. When you are memory-limited, you need different tricks.

Building a Self-Playing Chess Board Robot


The media in this post is not displayed to visitors. To view it, please log in.

As popular as the game of chess is, it has one massive flaw. This being that it requires two participants, which can be a challenge. Although playing chess on a computer against an AI has been a thing for many decades, it’s hard to beat physical chess boards that give you all the tactile pleasure of handling and moving pieces, yet merging the two is tricky. You can either tell the player to also move the opponent’s pieces, or use a mechanism to do so yourself, which [Joshua Stanley] recently demonstrated in a video.

There are a few ways that you can go about having the computer move and detect the pieces. Here [Joshua] chose to use Hall magnetic sensors to detect the magnets that are embedded in the 3D printed chess pieces as well as their absence. These sensors are mounted to the back side of a PCB which is also the playing field, thus using the silkscreen for the board markings.

For the electromagnet that moves the chess pieces core x/y kinematics were used to move it underneath the PCB, engaging when moving pieces but otherwise deactivated. This is all controlled by an ESP32 MCU, while the computer runs the open-source Stockfish chess engine. As the human player changes piece positions this is detected by the magnet’s presence, with the change input into Stockfish.

As the demonstration at the end of the video shows, it definitely works, yet some issues remain. Ignoring the mistake with making the near-right corners black instead of white, the pieces are large enough that e.g. moving a knight piece between others pushes them to the side, requiring these to be put back in place.

There is also no way for the computer to detect which piece is placed where, which can be incredibly helpful on some commercial self-playing chess boards like this for new players, as well as to detect invalid moves, but this might be on the list for a potential V2 of this build.

Best part of this build is probably the use of a PCB for the playing field, which would allow you to go pretty crazy with custom designs and colors, especially now that some PCB places are offering multi-color silkscreens that allow for custom graphics.

There are many adapters, dongles, and cables designed for interfacing display standards, and no doubt some of you have them in the glue of your entertainment system or work space. They’re great for standards, but what about something that’s not quite standard? [Stephen] has an arcade cabinet with a CRT that runs at an unusual 336 by 262 pixel resolution. It can be driven as 320 by 240 but doesn’t look great, and even that “standard” resolution isn’t supported by many dongles. He’s shared the story of his path to a unique USB to VGA converter which may have application far beyond this arcade machine.

We follow him on a path of discovery, through RP2040 PIOs, simple resistor ladder DACs, and home-made kernel modules, before he arrives at GUD, a USB display protocol with its own upstreamed Linux kernel driver. It’s designed to be used with a Raspberry PI deriving an LCD or HDMI display, but for his task he implemented the protocol on one of the more expensive STM32 series microcontrollers. The result after several false starts and some fiendish PCB routing is a standalone GUD-based USB-to-VGA converter that delivers perfect 34-bit colour at this unusual resolution, and also presumably others if required. It’s a worthwhile read for the many hints it gives on the subject of driving displays, even if you’re not driving an odd cabinet monitor.

Is That Ancient Reel Of PLA Any Good?

When it comes to knowledge there are things you know as facts because you have experienced them yourself or had them verified by a reputable source, and there are things that you know because they are common knowledge but unverified. The former are facts, such as that a 100mm cube of water contains a litre of the stuff, while the latter are received opinions, such as the belief among Americans that British people have poor dental care. The first is a verifiable fact, while the second is subjective.

In our line there are similar received opinions, and one of them is that you shouldn’t print with old 3D printing filament because it will ruin the quality of your print. This is one I can now verify for myself, because I was recently given a part roll of blue PLA from a hackerspace, that’s over a decade old. It’s not been stored in a special environment, instead it’s survived a run of dodgy hackerspace premises with all the heat and humidity that’s normal in a slightly damp country. How will it print?

It Ain’t Stringy


In the first instance, looking at the filament, it looks like any other filament. No fading of the colour, no cracking, if I didn’t know its age it could have been opened within the last few weeks. It loads into the printer, a Prusa Mini, fine, it’s not brittle, and I’m ready to print a Benchy.

My first surprise on printing the Benchy is that it’s a pretty good print. Received Opinion tells me that PLA is hydrophobic, and if you leave some out for a decade it will absorb so much moisture as to be unusable. In fact I was expecting a very stringy print indeed because I’ve seen that before with filament left out for about a year in the damp British climate. But this Benchy had almost no hairiness, its only flaw was a little bit of collapse along its prow line. I know the Mini isn’t at fault here as I’ve seen it print a flawless Benchy with new PLA, so that’s strike one to the ancient plastic.

Manipulating the Benchy, I found strike two. This is a reasonable print, but with not-too-hard pressure on the cabin I could snap it. The layer adhesion wasn’t as much as it is with a new-filament Benchy, and it has broken cleanly along the layer lines in the cabin pillars. Since snapping a Benchy isn’t a quantitative measure of how much the layer adhesion had degraded, I decided to formulate a test for layer adhesion. If I print something designed for measuring layer adhesion failure in both this old PLA and some new PLA, I can compare the two. It’s not perfect as I don’t have a new reel of the same formulation as the old stuff, but it’ll be close enough.

Punishing Prints, And Risking Holes In The Floor

What I have come up with is a 150 mm long box section with a 2 mm wall. If I clamp the first 5 0mm to the edge of a table, I can apply a force to the far end of the 100 mm poking out into free space, and find its breaking point. To that end I’ve printed two, one in my blue old PLA, and another in brand new grey PLA. I’m dangling a collection of angle brackets each of which weighs 130 g from the end of the box section, and adding brackets until it breaks.
A 3d printed box section clamped to a table, with a piece of steel rail suspended from itI couldn’t even break the new filament print with a floor-damaging 3Kg piece of rail!
I had only twenty brackets, and as expected the old PLA broke first, at ten brackets, or a 1.3 kg load. My back of the envelope calculation from high school physics gives me about a 130 N force on the top edge of the layer boundary over the fulcrum on the edge of the table to do this. I ran out of brackets and other hardware to try to break the grey box section, and finally admitted defeat when it refused to break with a 3 kg piece of rail I’ve been hoarding to make an anvil dangling from its end. I have proved that layer adhesion with ancient PLA is more than three times weaker than on the same printer with new PLA. It’s interesting when examining the break, the layers have parted very cleanly, this is not tearing of the PLA but simply poor adhesion between layers.

In doing these experiments I’ve discovered, not unexpectedly, that ancient PLA isn’t as good as new PLA. I am assuming that this was as good a PLA as the modern stuff when it was new — indeed I remember printing back in the day and my prints seemed just as good as today. What does surprise me though is that how it’s deteriorated isn’t what I expected. It produces good prints in terms of their physical form, without the hairiness I was expecting. In turn I didn’t expect the prints with this stuff to be weak, so what’s going on?

When The Volatiles Depart, What’s Left?


PLA filament is not pure PLA, instead it has chemicals added to modify its properties. The most obvious one in this reel is the blue pigment, but others might modify its plasticity or melting characteristics, to name two possibilities. These are not going to be stable solids like the polymer, instead they will be volatile compounds which are capable of evaporating over time.

I’m no polymer chemist, so I’ll draw my engineer’s conclusions here and prepare for a roasting from the chemists if I’m wrong. What I think has happened is that the volatile additives in the filament have departed over the years, and both the stringiness in damp newer PLA and the strength in prints made with new PLA are as much due to their presence or absence as to the PLA itself. In my tests here I think I have seen something closer to PLA alone with the additive chemistry absent, and along the way I may have touched on why the manufacturers add it in the first place.

It’s likely few of you are printing using ancient PLA, so while interesting, these results have limited direct relevance to your printing. But I have to wonder whether there’s a lesson to be learned in filament storage, and perhaps using a warm environment to stave off moisture might hasten the departure of those volatiles. Perhaps the best thing is not to be a hoarder, and to use your filament up as quickly as you can. Meanwhile, this isn’t the first time we’ve ventured into backyard physical measurements.

ReMemory is the Amnesia-hedging Buddy Backup You Didn’t Know You Needed

What would happen if you lost your memory, even partially? With so much of our lives being digital, forgetting your passwords (or the master key to your password manager) could be disastrous. Haunted by that specter after a concussion, [eljojo] created ReMemory, a tool based on Shamir’s Secret Sharing to help your friends help you.

Shamir’s Secret Sharing, for the uninitiated, is a way to split up important data between parties so that the full picture is only available when a quorum comes together. The classic example is giving everyone a couple of digits out of the combination to the bank vault, but no one the full combination. Together, they can open the vault.

ReMemory works the same way. Rather than the combination to a bank vault, the locally-hosted, browser-based interface splits the encryption key to your sensitive data. If you’re old fashioned that might be a plaintext list of passwords, or for the more modern the recovery codes to your password manager. It could be literally anything, like your Aunt Edna’s famous cupcake recipe, which surely should not be lost to time.
Aunt Edna could probably handle this.
You can chose how many friends to split your data betwixt, and how many will be required to meet quorum– the minimum, of course, being two, but the suggested default is to split the data five ways, and allow decryption from any three parties. Each bundle includes the complete recovery tool, so anyone in your circle of trust can start the process of decrypting your data if they get the others on board. Since it’s self-hosted and browser based, those friends don’t have to be particularly tech-savvy, as long as they can be trusted to hold onto the files. Everything is explained in the readme included in each bundle.

This does have the downside of requiring you to have multiple close friends, at least some of whom you trust to come through in a crunch, and all of whom you trust not to collude behind your back. Still, if you’re the social type, this seems like it might be a useful tool. The code is available under an Apache 2.0 license, so you can audit it for yourself — a must for any tool you plan on entrusting your secrets to.

The best part of the sharing algorithm is that it’s not vulnerable to quantum computing. While [eljojo] was thinking of amnesia when he put the tool together, we can’t help but think this also solves the postmortem password problem.
