I also don't know about macOS compatibility, but I don't see why it wouldn't work. You have already ordered the converter anyway, so you will know some enough. ;)


Sounds like you need the DIN 240 adapter. Looks like that M122 board came with a 240 DIN cable. I know nothing about Macs.

Hello!

A week ago, I 'soft-launched' this new main site feature for Admiral Shark's Keyboards. The title is to the point regarding what it is, a timeline of what I think are important IBM keyboard events. An interesting and informative overview of the keyboarding history behind the company that ...

This period of time is quite special for IBM (membrane) buckling springs. Around 40 years ago from now (Q2 1984), IBM Wheelwriter and Quietwriter keyboard assembly production was cranking up. IBM Netherlands is sitting at the forefront of IBM's "new" membrane buckling spring technology, not yet ...

why would these keyboards before "general availability" have a sticker with a vendor code on it?


These are not keyboards before "general availability" (the first new example in my previous reply is a keyboard from 1987). What I meant in the conclusion is that "Keyboard/Model G" as a potential ...

I like it, except for the blue sticker. As far as I know IBM never used stickers like that, certainly not in the eighties. It has inspection date 9 10 10. It reeks of 3rd party service company.


I disagree, I've seen it in quite a few 1985-1987 IBM UK made Model Ms that don't have the simpler ...

Hello!

Almost a month ago, rocco_16v posted in the Help Dating a Silver Badge Model M thread something that gave us very concrete IBM-written evidence for the existence of "Keyboard G"/"Model G" outside some inner assembly rear labels found on IBM U.K. made keyboards in the mid-'80s. Seeing that ...

No worries. Thanks for looking anyway!

I have a couple Model Ms lying about and I'd love to help. If you don't hear from me, please message me in Reddit or here.


Thank you!


Here's a question: what about buckling spring typewriters?


Funny enough, I have way more photos of the bottoms of Actionwriter/Wheelwriter/Quietwriter ...

I had asked the archive personnel to look for any subsequent documentation regarding the Model G but they were unable to locate anything else mentioning the model G nor a subsequent keyboard modeling (H,I,J,K,L).


That's a shame, but thank you for trying. There are some other leads to explore ...

Hello! As part of an upcoming Admiral Shark's Keyboards report on the various uses of "Model G" on IBM Model Ms, I'm appealing for information from anyone who has a Model M that was:


Made in the United Kingdom
From 1985 to 1990*
Is an Enhanced Keyboard variant (101-104 key)**
Has a sticker ...

So I contacted IBM regarding this board and though they did look for anything related to it (thanks to the IBM Corporate Archives), sadly their records did not include any documentation that could help identify the board. But I had the opportunity to receive some awesome documentation that adds to ...

Very nice boards! Is that the numpad that came with the L40SX? Did you manage to convert it to usb?


Yes to both questions. It's fairly straightforward as it's an AT-compatible device but with a specific PS/2 plug pinout - the mouse's passthrough pins are in the usual positions with the keyboard ...

Yesterday, I attended a fairly impromptu keyboard meetup in Exeter, UK to represent IBM. I didn't want to take a suitcase with me for all the train commuting I had to do within a day, so I took what I could fit into a particularly large backpack. This meant no Model B(eam spring) keyboards, but I ...

Hi, did you make it run with the Arduino Pro Micro?
I have acquired three Bigfoots and would like to use the cheaper Pro Micros instead of the expensive Teensy or Micro (without Pro).


If you're using Soarer's Controller firmware, it can work but with one modification. The firmware's (at least ...

It looks to be IBM 5253/5254 . The terminal specifically looks like an IBM 5253 Display Station, which (along with its 5254 dual-operator sibling) were for the IBM 5520 Administrative System, a document creation, editing and storage system. They're interesting since the terminals look very similar ...

What this heck is going on here? This PCB is quite a bit longer with space for a number of unpopulated components, not to mention some other subtle differences in components. It seems that this controller layout was borrowed from early terminal models.


(Copying what I said on my Discord to you ...

My hope is that my Keyboard Directory will help with such questions in the future but it's still a WIP. There are only 4 unique F122s currently in it (can search "F122" to see them) but I'll work on them this evening so more may appear shortly. But in lieu of that, you're welcome to post a photo of ...

These are keyboards spanning 1949 to the present, covering IBM, its descendants and companies that have acquired IBM divisions, staff and IP. From the IBM 024/026 Card Punch Keyboard Assembly to the Unicomp Mini M and Lenovo ThinkPad X1 Fold 16's Bluetooth TrackPoint Keyboard and Stand... 70+ years ...

It was my understanding the solenoid activated when the terminal couldn't keep up with your key presses? I'm recalling from a YouTube comment I read years ago so maybe this is totally wrong.


They were called "clicker assemblies" (or some variation of that) and primarily used for engaging on key ...

Good to see you here!

I certainly think they're interesting (and I always defend that IBM buckling sleeve keyboards are underrated!) Thank you taking the time to post the membrane layouts - whilst I have M4s, I've been put off the idea of completely opening up the inner assembly in case I broke ...

Apologies for the poor photo for Type 5. They're not common and its really hard to find photos of them. The photo above is a (quick and poor) scale up of a photo from Unicomp's website in the late '90s. I have an example of Type 5 (a Quiet Touch NLynx Technologies brand P/N 301-5520-012 from the ...

A few years ago, I wrote a guide on the different types of 122-key Model Ms (aka, "M122s") explaining how there were four distinct types of them and how Unicomp later adapted some of the later ones to suit their needs. I've recently been revamping content on the entire IBM Converged Keyboard (the ...

Any idea what this here Kishsaver's layout was called? I think I've seen it described by IBM as a 4704 type something-or-other (searching DT isn't bringing it up), along with numeric names for its brother 4704s like the 77. I don't recall having seen the layout itself described, however.


I'm ...

A few weeks ago, I was looking for layout diagrams for IBM 3270 family terminal keyboards and I saw some specific names being used to describe styles of IBM keyboards that I don't think I've seen mentioned before (at least, contemporary in keyboard communities). IBM Base Keyboard and IBM Converged ...

Now up to $760. Besides the color is there anything else that differentiates this from a normal Model M?


From normal Model Ms in general? Mechanically, not really. Obviously, the general rule of thumb is that the earlier the Model M the better quality though. In my experience though, the ...

Something else no one has pointed out. The Unicomp Mini-M has lock lights. From the photos, it looks like the FSSK will not.

I know the original SSK did not have lock lights, which is why the FSSK does not. But I really like either lock lights. or integrated LEDs into the caps lock and num lock ...

Updates are live! Changes:


"How to get them" has been split so it's no longer a massive text wall. Two "Compatibility with..." sections and the "Can I make my incompatible keyboard compatible?" section were formed from it.
Created "How do I find out if new Unicomp already has one?" section to ...

(sometimes 3, depending on which keys on the matrix)?


Model Ms are always 2-key rollover. Rollover would be the guaranteed minimum achievable combo size for all keys, not the maximum in a certain scenario. For example, the matrix used in the Unicomp Mini M is theoretically capable of having Q-T ...

The PCBs are thicker but they still fit. I also installed one in my 2014 GE Medical Unicomp. You just need to use a worrying amount of force and come in from the right angle.


This was my experience as well. They fit, but something seems tighter. I tried 3 Unicomps (a 2019 Classic, a 2019 Ultra ...
