IBM 3101s were apparently once used as westlaw terminals

Another user has fitted an XT case onto a 5251, so (somewhat) similar concept

Given how tall beamsprings are, adding a wide area below the spacebar as a palm rest might be a good idea.

Good to know, thanks

pandrew helped me offline, I ended up building another controller (I had ordered multiple PCB's) and I got the one I built today working great. In fact, I'm typing this in on the model F. I'll spend some time to see if I can figure out what is wrong with the other controller - I'm curious more ...

Here's a model f with a bell, for lols

Here's a previous guide for converting a Dasher, using xwhatsit controller:

Thanks davkol; exactly what I was thinking.
Would be perfect if it has a scroll wheel too.

I'd also check if you slided the backplate all the way into position. If the flippers are somehow misaligned it could also cause extra keystrokes.

I get a suspicion that this has something to do with your Numlock status. If numlock is off, numpad 4 becomes left arrow, and alt+left arrow will trigger a browser back.

Agree that accuracy clicking is sometimes a problem, but the time savings for not having to move my hand away from home row to use the mouse outweighs this one flaw.
I also have a backup trackball for when I have to do mouse-intensive tasks (photoshop, etc).
Come to think of it, has anyone made a ...

Never seen a keyboard looking like that before. Interesting concept; wondering why it never got popular.


Cost is definitely an issue; it went for >1200 USD 5 ...

NOS replacement beamspring switch

Yeah, the paper label / birth certificate is what I meant.
This is actually the first f122 I've seen that doesn't have a laminated paper label, which is strange since I know many much later model m's have it.

Now we just wait for btc price to drop...
Very nice board, too bad the label isn't perfect. GLWS.

Final tally:
F107 3600
F122 445
F AT 268

Unfortunately no, the protocol is different. You will likely have to build your own converter, as I'm not aware of any converter that outputs XT scancodes.

He's got a NIB pingmaster too

Agree with kmnov. Designing a PCB and then solder on the hot-swap sockets will be the cleaner and more precise solution in the long run, and you won't have to hand wire anything, so less chance of the soldering joints coming loose over time.

After rust is removed there will likely be pits left on the plate, and exposed metal will not remain rust free for long. Some type of coating is usually needed for durability.
You can try to find a place to redo the Chromate conversion coating on the pate for you, but it probably won't be cheap.

I personally recommend wirebrush if you have large areas of rust, before soaking in evaporust.

Primer + Enamel has worked well for me, powder coating is even better. All depends on your budget.

2 hours into the bidding and we're already at over $300; wondering how high this one will go.

That one is 5v, so it probably isn't the one that will will want to replace an IBM solenoid. Also its probably going to be the size of a dime.

I'm not sure where to get model F style solenoids, I need some as well. I might have to resort to making them myself :shock:


You dont need to make ...

Exciting news! Looking forward to the review.

Do you guys make curved plates?
Would love to get a Model F top plate like this:

Another gen 1 M122 with F-122 style feet

I asked JLCPCB to build me some FEXT PCB (101 key) with 0.6mm thickness a while back, and they rejected my order saying that the possibility of warping is too high. I imagine that a 122 key version is even more problematic.
You might need to ask a few PCB manufacturers before finding one that will ...
