For un-bricking, this might be helpful, if you got a Teensy at hand:

If you want to have one for 20 euros, without converter, dirty and non tested ( ;-) ) let me know.
That would be my general idea, yes, as for some bizarre reason I can't really find out I, too, find it fun and relaxing to take these things apart and augment them, as we both know ;)

Presumably, the first picture was just taken from somewhere else, because it looks "close enough" (and better than what the seller had).

Careful with these cheap chinese things, they normally come with a practically unusable firmware that requires a strange Windows program to work, or reflashing to work with AVRdude (i.e., you need a programmer to program the programmer ). Been there, done that

I'm a bit unclear about the current state of affairs. i$, dou you have the 4, or are they still at the seller's, or are they gone? If still at the seller's, do you have a contact address?

It would be a good idea to include the possibility to add an ISP connector on your board. Rarely used, but makes life much easier if you need to reprogram the boot loader (or want to remove it entirely and use all the space for your application).
Layout is like this (view from top):

I guess that the IBM engineers never thought that this plastic would survive connected to a computer 25+ years
Presumably, 10 years MTBF was the goal defined by the IBM engineers. That's already pretty ambitious, but "planned obsolescence" wasn't so important back then. I'm sure that, as with some ...

"Trio Mate" is the name.

No paint job. Just dust.

[Edit:] Yes paint job, I stand corrected. See below; mental note to self - never only look at the top part of the picture!

I've got one here (rubber dome Model M, that is); you can. My one has 1-part key caps (so, stem and cap in one), but you can still simply take them off. There's a rubber dome instead of a spring below; that's the big difference.

And I'm not a 'he', BTW ;)
Sorry for that; glad to read that you're not offended.
Well, live and learn ... from now on, I'll use "the original poster" instead.

ANSI IBM M is not that rare at all, not even in the EU! :? I read what she wrote!
Ive been following eBay for quite some months now ...

Nothing that would have reached me.

"ANSI US layout", he said. That is rare.

The big (IMO) downside to this design is the power hungry original IBM controller board. Even with the very large battery, it won't last more than a day without reloading.

Rubber domes (like buckling springs) have membranes. Here's a shot of those inside of one of my Model Ms:
http://deskthority.net/resources/image/9892 There's 3 layers. A middle layer with holes, and 2 silver coated layers — one rows, one columns — which are held apart until pressed.

All it ...

I also noticed that I created more pressure with the screws that with the bolts. I had to lose them to have the keys properly working. In particular the long keys (Enter, shift, backspace ...) were too hard and got stuck. It took me some time to understand the problem.
I've noticed this problem ...

"I just found ..." means you haven't ever used this keyboard before, right?
Is it directly attached to a PS/2 port on your PC, or via some PS/2->USB adapter (including KVM switches)?
Do the offending keys work correctly after having been pressed once?
Does it work correctly on another PC?
Unless it ...

Those look like genuine white Alps switches - I can't tell from the picture, but it looks like it says "ALPS" on it. The keycaps are doubleshot too. Might be worth something to a German ALPS enthusiast but I'm not sure how much. I'll wait for someone else to give a definite answer.

Obviously, the previous owner had the same idea

This one looks nice. You should pop off a cap and show us the underside of it, as well as the switch itself. Not sure about the price off-hand without.

The Wiki says that it should be one of these: http://deskthority.net/wiki/Alps.tw_Type_T5 - clicky and ...

Hi All,

I've recently acquired a set of mechanical keyboards; bought it because it contained 3 Model Ms. The rest is completely uninteresting to me, but since some of you might think differently, here they are (state as shown):

That would be great; thank you.

Had a look at his controller at all?
No, not yet.
Decompiling his firmware, modifying and redistributing it is not a polite, nor particularly legal thing in many countries. I'd suggest that you retain your personal copy until such time as the source is actually released, and apply and then fork ...

Does anybody know where he is and/or can point him here?

I'm in a rather big dilemma at the moment and would need a word with him ...

because, you see, I've reverse-engineered his converter. 100%.
I would like to publish the source and/or the binary images, because it's already at a state where it ...

Where did you see that?

Methylene Chloride isn't something you should get on your hands or into your lungs (amongst other niceties, it's suspected to be a cause for cancer). That's quite heavy stuff. Banned for consumers in Europe since 2010...

This resistance thing surprised me quite a lot, too, when I did my first bolt mod (not out of fun, but because somebody's drink of choice shortened some paths on the matrix), but if you measure it across some perfectly functioning original traces, you'll find that the original conductive paint has ...

You know, this makes me wonder if I can hook a R2R to my 5150 or VIC-20 or whatnot. Questions, questions, questions.

I'd be very interested in how this 2009 patent application holds up. Adding a set of diodes to the keyboard matrix to prevent ghosting definitely falls under "prior art".
