Ask HN: IBM Model M Keyboard Alternative?

23 points by laserstrahl ↗ HN
I heard about Unicomp's Keyboards [1].

But since there's no used to sell, i wantes to look for IBM Models M orginals. My question is:

Which model to avoid? Are there any? Would connect it to a PS/2 adapter.

I don't like the normal mechanical keeb market, because they're loud.

Well, original Model M's are loud (clicky) so maybe you won't like them, and the new Unicomp oones are said to be even more loud.

A known refurbisher of M models is:

the name should tell something.

There is a thread on HN revolving on M keyboards talking also of PS/2 to USB adapters:

I am yelling 'Thank you' from the back.
My Corsair K63 is much quieter than a Model M. No need for a din to USB converter either.
> I don't like the normal mechanical keeb market, because they're loud.

Buckling springs are way louder than almost all mechanical switches on the market.

I don't see any rational argument for a Model M in 2023. There are so many options in keyboards that are more modern, quiet, well built, compact and yet feel nicer to type on.

Nicer to type on is subjective - for me the Model M is about as good as it gets, in terms of feel. To be honest (hot take) I even prefer it to the Model F.

That said: yes, they're extraordinarily loud. OP you're barking up the wrong tree if what you don't like about other keebs is their noise.

I do not see any rational argument for a Model M. I started on a PC then to XT, then to AT... I had two Model Ms and a clone model M. I had a choice of over 200 keyboards... I chose the G101 -> $31. It has the right feel for me, and its very quiet, I haul it around with my ASUS ROG laptop. At the desktop, I am using a white Dell KB216. Very light, and easy to clean.
> I don't see any rational argument for a Model M in 2023. There are so many options in keyboards that are more modern, quiet, well built, compact and yet feel nicer to type on.

This is a highly subjective take. Just taking myself as an example, an original Model M feels far nicer to type on to me personally than any of the other modern mechanical keyboards that people often recommend.

There are absolutely rational arguments for a Model M. Just as there are rational arguments for other keyboards too. You just have to try to look at it more objectively and try to match to people's own unique personal preferences.

The fact that it lacks Super keys is one non-subjective argument against it.
I just remap CapsLock to Super.

Built in function in Linux and macOS; on Windows, SharpKeys puts a dead easy GUI on the built-in Registry key.

Means I get rid of CapsLock, puts Super where Unix keyboards had Ctrl, and I keep Ctrl and Alt where they belong. Works well for me.

I mean, they lack a Right Super key (AKA menu key) and so on as well, but I have no need of anything else, TBH.

While that is obviously a detractor that I would agree with, how much it affects you will vary from person to person.

Again, just myself as an example, I've been somewhat surprised over the years how little I've actually needed a super key.

On Mac OS, my preferred keybindings was to have Command bound to both left and right Alt keys, Ctrl kept as the left Ctrl key, while the right Ctrl key was rebound to Option/Alt. Some people also like rebinding the usually-useless Caps Lock key but I am one of those weirdos who doesn't like doing that.

I've moved back to Linux over the past couple years and haven't found the need to do any rebinding to get a Super key on my keyboard at all.

Your mileage may vary!

Back in those days I had Northgate keyboards. Those were keyboards you could use to smash other keyboards to tiny bits and go right back to typing. But it's true, today you can get some pretty nice keyboards without having to try to retrofit a 30-year-old bit. And a much wider array of key types and layouts.
Take into account that old Model Ms tend to have their plastic rivets fail: those keep the sandwich plate-membrane-plate together, and after enough of them break some keys stop registering. There is a laborious fix, called “bolt-mod” which consists on drilling the rivets off and putting bolts with nuts instead.

So, you either get one whose keys have all been tested to work, or you should be ready to do some manual work.

As far as I know, internally all models (M122 terminal, standard Enhanced Keyboard, and Space Savers/TKL) are internally the same w.r.t. reliability, noise, and feel.

I guess the important thing is why someone is buying it.

you should be ready to do some manual work

Reasonable if fixing broken machines is something a person likes to do.

In that case, looking for one that's clean and complete and faulty and cheap is the way to start.

Just an anecdote about the Unicomp Model M's.

I treated myself to one about four years ago. After many years of telling myself it was too expensive.

It was complete crap. I mostly kept it in its original box except for fooling around with it on an rPi. It failed in less than two years.

I sent it back for repair under warranty. The warranty required I pay for shipping it back. Another twenty-five bucks down the drain.

A few weeks later its back. In the interim, I am poking around on the Unicomp website and notice that it lists the weight as...I don't remember, but like five or six pounds.

The one I bought from Unicomp weighed in at just under three. I remembered when the Unicomp arrived and thinking it felt light and flimsy compared to my memory of the original Model M I'd had back in the 1990's (salvaged from a 8580 headed to the dumpster).

I got the replacement back and sell it on eBay to cut my losses.

I bought the Unicomp before the pandemic, so it wasn't a supply chain issue. Just a company maximizing profits. Requiring customers to pay for shipping under warranty is probably a sign that the company knows it will have a lot of warranty repairs.

My advice is don't buy a Unicomp. But YMMV.

I have tried just one.

I concur. Not a patch on the real thing.

I had two crap Unicom’s, and they also refused to pay for shipping when they broke.

I then heard that they revamped the e keyboards and I tried again. This one has been problem free for a few years now.

That's a damn shame, I bought mine in 2007 and it is still actively used and awesome.
In the end I bought a Hermes Baby typewriter and got a tactile writing experience.
The parent comment is a bit hyperbolic and under-informed, so let me try to provide some color on the Unicomp brand.

I own a half-dozen Unicomp keyboards, have used original IBM Model Ms, Model Fs, and has a pair of the Model F Labs F77s, so I have some familiarity with buckling spring boards.

Unicomp's manufacturing equipment came by way of Lexmark and the quality suffered as the tooling aged. They replaced their tooling in 2020 when the shipped the New Model M. Fit and finish is much improved since then.

From Wikipedia:

"Unicomp continued to use the original IBM machinery to produce Model Ms, leading to a gradual decline in quality as the tooling became worn. This, and various problems with their USB controllers helped keep a market for vintage Model Ms thriving. In 2020 Unicomp replaced its tooling and shipped a "New Model M" with noticeably improved build quality that more closely resembles the classic 1391401 (though with a 104- or 103-key layout and USB); many older variants are no longer sold on Unicomp's website and some still on sale have been deprecated."

There are a few issues with the Unicomp boards:

1. Thinner plastic cases and a lighter backplate. The case was improved with the new tooling, but the backplate still changed the feel compared to the originals. 2. Plastic rivets breaking. The board itself is sandwiched and held together with plastic rivets. These rivets will eventually start failing, which leads to key detection issues or complete board failure. They have to be bolt modded to fix this. 3. Non-customizable USB controller. Programmability has become expected with mechanical keyboards and other than Unicomp themselves flashing a layout at the factory there's nothing here.

Customer service from the company has always been excellent, in my experience, but it's definitely a firm that gives the impression of trying to keep the lights on for 30 years and just barely making the margins pencil out (thus paying for return shipping).

Some people really love buckling springs. Unicomp makes a decent board that gets you that for a price less than $500, but if buckling spring isn't your terminal value in a keyboard, consider one of the dozens of excellent mechanical keyboards out there with modular key switches.

I checked my records. I bought it in 2020. So it was the “new model.”

The keyboard Unicomp sold me was complete crap. It failed after a dozen hours of use (just being plugged in to an rPi is in that number) over a few months. Otherwise it sat in its box on a shelf.

I was into the original keyboard for $150. Another $28 for shipping under warranty.

It didn’t feel like quality.

It didn’t perform like quality.

Unicomp didn’t stand behind it as if they believed it was quality.

I bought a Unicomp 15 years ago, no regrets. A couple years ago i had to replace it (a couple dead keys) and 8 keys on the new one didn't feel right. Kind of mushy and wiggly when fully depressed? I swapped in the keycaps from the old keyboard and now they're fine. This keyboard has a date of 2/25/2020 but my issue was with keycaps so no idea when they were made. In 2038 when this one dies I'd prefer to buy another Unicomp but we'll see.
Get Leupold f660c with silenced topre switches.
The Leopold F660C keyboard with Topre Silent 45g switches isn't silent, but it's an obsession killer. If one want custom QMK firmware, get the Hasu aftermarket controller.

https://1upkeyboards.com/shop/controllers/fc660c-controller/

I too have a closet full of mechanical keyboards, somehow indulging the obsession while failing to see the point. A Topre switch is so much better, it allowed me to focus on my layout then get back to work.

A fellow man of culture.
Model M and Unicomp keyboards are way louder than typical Cherry MX and similar keyboards. It is very apparent from watching some videos on Youtube. For a completely silent keyboard check out the Realforce R2 (PFU Limited edition): https://fujitsuscannerstore.com/cg01000-290301/ It goes on sale for $220.
I second the Realforce R2 recommendation :)
They are loud. I have a Unicomp I bought about 18 years ago. It has been rock solid, but if you don't want loud this isn't they keyboard to get.
I use the WASD compact keyboard and am quite happy with it. Got the quiet red switches with the rubber dampers and it is almost completely silent. Quieter than the buttons on my mouse anyway.
> I don't like the normal mechanical keeb market, because they're loud.

Happy owner of 5 original IBM Model Ms here, plus Das Keyboard, Apple Extended, 2 x Apple Extended II and others.

If you don't like "normal mechanical" K/Bs because they're loud, you will not like a Model M. They are much, much louder. I don't know any 21st century keyboard that's as loud as the real IBM deal.

When I moved to Czechia in 2014, I took a Model M in my suitcase, in the spirit of "accept nothing less than the best."

People crossed the floor of my open-plan office with 40-50 co-workers to ask what I was typing on. People multiple rooms away asked what the noise was. My boss' boss, in his own private separate room, said my "typing sounded like rain." Heavy rain, outside, he clarified.

But remember that the Model M (and the F that it superceded, which was if anything even louder) was released into an environment where the default "keyboard" sound was that of a Selectric typewriter or Teletype unit! These weren't "quiet" devices by the standards of their day, but they certainly weren't seen as especially noisy.

Offices used to be very different places, acoustically.

Oh yes. I am an official Grumpy Olde Pharte and I remember working in the 1980s, in an office full of the things... and a computer room full of people hammering away at DEC VT200s and the like. Noisy as hell but we filtered it out.
My Brazilian 8-bit MSX back in the 80s, by default, emitted the sound of a typewriter, through the TV speakers, for every key pressed! tek-tek-tek...
Agreed. The switches on Model M are loud as hell, and those big plastic cases they used on various vintage keebs give them a real growl you don't get on more modern cases that tend to be smaller and/or machined out of solid metals. I'm not an audio engineer, but seems like the cases act as a resonance chamber and give a really unique sound signature.
As others have said, Model M are very loud. What I wanted to add - is that it’s one of the most prominent reasons for its appeal. The “kachung” sound accompanied by the subtle whine of the springs the space-bar makes triggers a bout of nostalgia growing up with a PS/2, and is the primary reason why I personally want to one day possess it again, and until that day fill the void with still loud, but less satisfying alternatives.
Oh my, yes. :-)

I actually don't like using them on my Macs.

The key feel of a Model M tells me I'm on a PC, or a Unix box.

The key feel of an Apple Extended tells me I'm on a Mac, and I hit different combos without thinking of it. Cmd+C/V/X instead of Ctrl+C/V/X etc.

Put the PC keyboard on a Mac and my muscle memory gets very confused...

If you want a quiet keyboard get one with Boba U4 switches.
I'm something of a keyboard collector..

I have the OG model M from 1993 or so, the Unicomp Model M, and a Model F keyboard from modelfkeyboards.com.

Of the 3 my favorite is the New Model F. It has a satisfying ping-y The Model M is good too, but the cable is fraying and I'm afraid to use it and accelerate its demise. Probably I can send it to someone for fixing or fix it myself somehow but haven't gotten around to it.

Nothing is wrong with the Unicomp technically but it is my least used... not sure why.

If your complaint about mechanical keyboards is that they are loud, be prepared that the buckling spring keyboards are several times louder than anything Cherry-like.

On the other end of the spectrum I have a Realforce R2 PFU edition. It has silenced topre switches which are sort of a fancy rubber dome. This is the keyboard I use 90% of the time and for this comment.

I have an original IBM AT Model F which I used on a Mac with a AT->PS/2->USB pigtail in the mid aughts. I sometimes think back to what an insufferable ass I must have been to have exposed my co-workers to that interminable cacophony of self-important keyboard clacking.
Ha.. never even seen that AT connector! I can't believe you would type on that around another human being, it's like explosions going off!
Model F is $400, that's basically a collectors edition you put for display and never use.
It was expensive, but it's supremely satisfying to type on such that.. I want more! But I think my days of buying expensive keebs is behind me...
> but the cable is fraying

Unicomp has a repair service to fix old Model M keyboards. They will even clean them and upgrade to USB! I just sent in my two Model Ms from the 90s yesterday. It's a bit expensive but if what you want is a classic Model M, there's not much of an alternative.

I've had two Unicomps over the years and they treat me very well.
Never understood the appeal oft mechanical boards. I've tried them often but always come back to low profile rubberdome keyboards. Cheap, disposable, comfy and I can't type faster on anything else
There's nothing disposable about a keyboard. They'll take hundreds of years to break down.

Get something that lasts instead piling onto landfills.

>Would connect it to a PS/2 adapter.

Yes and no. Some PS/2 adapters can be flaky with original Model M's because of the heavier power draw from the older chips compared to modern IC's.

>I don't like the normal mechanical keeb market, because they're loud.

Buckling springs are about the same volume as the Cherry Blue's I've tested.

I don't like the normal mechanical keeb market, because they're loud.

Try non-blue switch options; I love my Logitech G915 Pro for example, although its the midway brown switch and a very different profile; but there are plenty of others that will be more like the classic style and (relatively) quiet.

Get a Model M and some noise-cancelling headphones ...
I don't think noise-cancelling will work. Clicking noises are difficult to cancel.

You need good passive protection, shooting range earmuffs may be a solution. I don't recommend the active ones though as they are designed to let voice pass though, which mean you will still hear your coworkers yelling at you and your <censored> keyboard.

I've used mechanical switch keyboards in the past. I can't be sure whether the tendonosis I suffered from was caused by the keyboards or something else, but after cutting out other probable causes, going through course(s) of medication, and using wrist supports and splints I moved to a cheap wireless keyboard and mouse combo and all pain disapeared. I've fully embraced the wonderful mushy, smudgy goodness of my keyboard now.

Edit: am Emacs user.

The vintage IBM keyboards are romanticized quite a lot. They feel great to type on. They suck for gaming. They're very loud (that being your issue with the normal market is weird since you want one of these things..) I'm not willing to go without a windows key these days.

I used one of some variety or another at my job about 10 years ago working at a helpdesk. It made a good conversation piece, but eventually I got tired of the conversations and users on the phone could hear it too.. sometimes not for the best.

I went into this rabbit hole for a bit, I had bought I think four or five vintage Ms varying from the 80s to early 90s when Lexmark took over (Blue IBM logo, drain channels on the bottom), three Unicomps (two full size models, 104 keys, one USB one PS/2), one space saver model. The space saver model I bought for my mother that was teleworking; it randomly failed at some point after a couple of years and I was never able to figure out why, there wasn't a spill or anything that I could find evidence of.. I never looked into repairing it, just got rid of it.

The Unicomps were okay. You can tell that the molds and tooling they bought from Lexmark are pretty worn now, and the weight has been reduced even further no doubt in an attempt to be price competitive with the current market which isn't easy. I still have one of them and it still works, the other I lost due to damage that can't be levied against the keyboard.

At some point though I just got sick of the noise. At this point for old mechanical keyboards I'd sooner seek out a Dell AT101 than using another buckling spring board. It uses Black ALPS switches, they are tactile with a much fainter sound that I enjoy, and they're equipped with Windows keys. I have one Model M connected to a file server at a remote site that I touch maybe once or twice a year, I'm reminded at these times of why people love and why I no longer care for them.

My current keyboard is a Ducky Shine 7 with Cherry MX Blacks. Blacks and Browns (or comparable from the many other suppliers that have cropped up in recent years) are the only ones that interest me.

If you really want a model M look around on the used market and don't obsess over which model you are getting. They're all variations of one another with some cost cutting added here and there but imo they never compromised the solid feel of the keyboard or the fantastic tactile click of the keys.

Can't comment on IBMs but programmable keyboards have been a revelation. I thought 34 key keyboards were a joke but after getting a ferris I now have layers for numbers, symbols, navigation and media all under the home row with home row mods. I don't have to stretch for anything any more.

I think a concave ferris with 3 thumb keys or an extra outside column would be the sweet spot, or a more staggered corne.

I have the silent version of the HHKB and would recommend it. I didn’t want to give over that much desk space to a full size keyboard (and use a trackball). My previous non-silent HHKB still works just as well as it did when I bought it about 20 years ago.
>I don't like the normal mechanical keeb market, because they're loud.

Then install dampeners and use silent/non-clicky switches? This seems a very bad reason not to use a mechanical keyboard.

There are also other options, e.g. for modern rubber dome keyboard (like the HHKB).

Context: I've been programming with a Model M for 10+ years now.

If you don't want a loud keyboard, then you do not want a Model M. They're probably the loudest keyboard you can buy today (excepting something bespoke that's intentionally louder than a Model M).

That being said, any of the 1980/90s PS/2 models will probably be perfectly fine, as long as you find a reputable seller. I bought mine (early 1990s) from eBay for about $50 in 2012, and haven't had any problems since.
