So i've "found" a Cherry / Compaq G80 11800 in our server room, not used anymore. I remember typing on this device before being keyboard addicted - but only a little bit when there was a real problem which could not be solved with remote connection. I don't really know what to do, but i love the bottom-out sound of these brown switches, and could use many of the Skidata keycaps on it, maybe make some weird switch combinations and playing with a Teensy.



I have not cleaned anything, and want to fix the board on a piece of wood. I've already cut two pieces today, one the full length, and one width without the ten-keys. I don't know yet, if i should make a TKL out of it! It looks very clean on the back, and just two arrow keys go through the ten-key numbers, but i would not really know what to do (but read the other TKL selfmade threads here).

You can make it tenkeyless by cutting between the 741 and 852 columns on the numpad. No soldering would be required to keep the rest of the keyboard working.

On my Compaq MX-11800, I did that, and then I cut away some more and glued a new six-key cluster to the right of Return and Backspace, but that required some more wires and the resulting wire mess is not pretty.

Rerouting the cable to the left looks like a good idea. My cable is quite a tight fit, being still on the right, out the original hole.

I had dissolved parts of the ABS case in acetone to use as putty, but it did not turn out as seamless as I thought it would.

I didn't see this thread before, thanks for the link. A fine mod you made back then! Noone bought it? I will also cut away the number block, and have to do this jumper wire job.

Thanks!

I did cut through the middle of 741 as you can see. Regarding Findecanors post, I can't remember whether it would have worked without the jumper wires, if I had cut beneath 741. In my case the case modification layed the cut line onto the PCB. As PCB revisions may have a different tracing anyway the talk about that is rather pointless. I sold it some days after that as someone found the thread, iirc for 20€.

Yay, it works! I cut trough the middle of 741, and used a Teensy.

I wonder... for what is the teensy?

Custom key layout (the keyboard has no win keys), macros, USB support, or maybe even to make the keyboard smaller by cutting off the top row (where the controller is connected) and hooking in a Teensy as new controller?

Lots of reasons.

as for now I guess it's for simple USB conversion... nice job. Did you have to jumper wire, or did it just fit because you left 741 intact?

As a PS2 / USB Converter, for learning, just playing and try out, never soldered before (bought an iron, and stuff). I don't really have an idea what i will do next with this project.

I think it fits for now because i left the 741 intact.

So that's what i've done so far. It's just a 'Skeleton' case for my G80-11800. I'm not finished yet, but i like it. Between the PCB and the wood there is a flexo printing plate cut out by a Kongsberg cutter.

It's not to bad, fun to play around with switches, caps, will be a Frankenbord or something like this.



I used a piece of wood from IKEA, which i found in our kitchen, and bought now another one. Maybe i will not cut the wood as done before, and screw the PCB on the top to have about 6-7cm palm rest.

Wow, that looks fantastic! Very professional-looking. I'm quite jealous.

Does indeed look very cool. I wonder how it feels, after all they're just plate mounted and screwed to a piece of wood. Then again the original 11800 feels amazing imho. The browns feel so much better than in my Kinesis.

Very nice! you did a great job, looks really clean

Nice use of the OG Skidata set as well

I put a polymere plate (normally used for flexo printing or stamps) between the wood and the PCB, with a thickness of 2,54 mm and a maybe 0.3-4 mm thick adhesive tape. That dampens a little bit, and feels 'normal' now i would say. I tried different thickness of the polymere plate, started with 1,14 mm which is to thin, and 5 or 6 mm plates, which are too soft.
I'm typing on it like 'CLOCK CLOCK CLOCK *space* CLOCK CLOCK CLOCK'

Any chance I could get the teensy firmware that you used? I'm thinking about doing something similar with my board.

Simple as that: http://deskthority.net/workshop-f7/xt-a ... t2510.html

thanks man!
