Whoops, sorry for missing replies!
Thanks for the warning!
My keyboard looks like this from the outside:

With removing the keys you didn't mean just the key caps, right?

This is the backplate view:

Now I know what you mean. :-(
What about an isopropyl alcohol bath?

Would that damage anything?
Isopropyl alcohol can't really damage anything (except perhaps paper, or in extremely high concentrations, idk - ymmv), but I'm sure you figured this out by now (long time since your post). It's an excellent cleaning solution (pun intended).
* EXCEPT the space bar. That one is a bit tricky to remove and re-attach, it is better to carefully release the spring when opening the keyboard.
Not true - the XT and AT (and possibly one or two terminal variants with a comparable layout) are the only Model F boards with this design, due to the abnormal length of the spacebar. All terminal boards which use the smaller more normal spacebar use normal stabilizers and can be handled like any normal key.
well i ll buy in few hours a terminal model f 3477 or 3487 and, no i dont hate myself and i am not bored but its still to awesome to do this and use it at a regular pc :D
damn that numbers are not listed in here, would this keyboard work for a RJ to PS2 soldering?
Those terminals use the keyboards with the modular plug ("RJ" not-quite-correctly, but in common use). They are adaptable but I don't have a pinout for you - but this next reply I'm mass-replying to might very well detail it, I haven't read it yet.
Hi everyone,
I am Ralphies from the Netherlands. I saw at my work an old terminal keyboard, it was a model 1394167, it has a RJ45 telephone look plug.
Just like this borrowed picture (picture snipped)
Today I took a ps/2 cable from an Compaq keyboard and used this cable to mount it on the print of the IBM terminal keyboard.
Here some pictures taken when i openend.

I got one yellow cable (= shielding), another yellow cable, a white cable , a red cable and a black cable.
As I examened this post with 122 keyboard, I hope these cables where the same layout as mine. I can find no schematics of my keyboard.
But assuming shield = yellow, clock = other yellow cable, ground= white, data=red and +5V= black cable.
Then I took clock (yellow) to pin 5 (see piucture below for ps/2 diagram).
Ground (white) to pin 3
Data (red) to pin 1
+5volt (black) to pin 4.
And offcourse the yellow IBM shieldingcable attached to the shieldingwire of the Compac ps/2 cable.
I measured with the multimeter before at the compac cable which cable belonged to which pin of the PSD?2 connector.

But nothing is happing, computer starts up, gives an keyboard-error, but when getting to my grub , no arrows buttons working and after some time my ubuntu comes in but no button of this keyboard will work at my ubuntu login screen.
Is the 1394167 terminal not usable for a pc?, or do I have the wrong cables attached to the ps/2 cable (like in diagram)?
Greetings from the Netherlands.
That initial photo sure looks familiar, like perhaps I was the one who took it :) Greetings, indeed.
I went on to sell that exact pictured unit, 1394167, to another geekhacker who proceeded to cable mod it and he did succeed with getting it working on PS/2 as I have documented. It is a compatible model. However, your 'keyboard error' is due to the issue I mentioned, where the reported keyboard ID is not an expected/valid ID (and/or you might have clk/dat reversed, I'm not sure of colours/pinouts for those keyboards - I did request documentation from the person I sold the board to but I believe he went inactive and disappeared).
Please keep me updated with any progress you make. After I post this reply I might spot something jumping out at me and reply again just to be sure I'm fully clear on the way you're hooked up.
No, you have to create a *signal converter*. The issue isn't a different port, the issue is a different signal.
You can use them with a PC by bridging a converter [between the controller and preferably ending out into USB] made from a teensy or something (or if you're real clever, create a whole new controller compatible with USB or PS/2).
But most people make the converters out to USB rather than PS/2; not sure if anyone actually made one in PS/2 come to think of it.
You should know better than this - these boards are quite usable on PS/2 or AT, with appropriate software hackery.
However, I am now 'deprecating' this method overall - the USB converters, such as Soarer's or dfj's, are much preferable in almost every way. They are simple to assemble and program and simple to use. While not cheap, they are definitely inexpensive.
