Hi. I've laid out a version of this for model f at, if anyone is interested. Tested and working fine. https://raw.githubusercontent.com/frogmaster/TH-XWhatsIt-F/main/model_f_at_board.jpg Kicad files and gerbers can be found here: https://github.com/frogmaster/TH-XWhatsIt-F Minor change from my teste...

I had a unicomp board, where i had a similar but much worse issue, where left arrow would fire when pressing rctrl. It was not immediately apparent, but there was a very slight bend in the backplate, the issue went away, when I massaged it a bit.

B and N are just at the end of a row on the membrane matrix, so it's quite possible that the trace has corroded there. You can't know without opening it up though, so follow Wheezers advice, but if the membrane isn't working and couple of days in some dry warm place doesn't help... Then I'm afraid, ...

I'm interested, give me couple of days to do a little bit of inventory and see what exactly i need.

Thought i'd share my experiments with idye poly and old ibm keycaps. Caps painted are all from some Model M. Could not bring myself to dye model F keys, yet at least. https://drive.google.com/uc?export=download&id=1YE0bDKs9JRrOgFEBtMvq8F9eMZfV_Y0G The blue gradient starts with turquoise and ends wit...

Added the keys to keymap editor. It should make easier to remap hidden keys of IBM AT keyboard. Can you try this? You can load your existent firmware file at "Base Firmware File:" section and the editor should display your mapping correctly. http://www.tmk-kbd.com/tmk_keyboard/editor/unimap/?ibmpc_...

frogmaster, Oh, AT keyboard. I assumed your keyboard is XT becasue you refered process_cs1. I didn't realize missing keys on AT editor but I'll add them. The misssing keys are 39 and 68 in scan code? Is there any other? https://www.seasip.info/VintagePC/ibm_6450225.html And can you post pic of your...

Thanks hasu, got it to work. If someone get's stuck with modified IBM Model F AT 84-key, then i did the following remaps, i used 32u4 full-key keymap editor: To get ISO enter, ISO left shift and standard caps, ctrl, alt positioning LEFT -> ISO # ISO # -> LEFT INSERT -> RALT LGUI -> LALT RCTRL -> CAP...

Well for start, EXTRA_INSERT (0xb6) is missing from numpad (should be left of NUMPAD 0). What is the button i should select on the editor? Also, what are these mapped as on keymap editor keyboard? I was trying to grep these values in ibmpc_usb.c, but only one that showed up was 0xB6, which seems to ...

I'm in the process of restoring a model f at for everyday use, and was thinking of using this, but i have modified the layout to suit my usage, and have verified, that the following Soarer's remap works: remapblock EXTRA_LALT LALT # extra pad lhs of space EXTRA_RALT RALT # extra pad rhs of space EXT...

I would be interested in one, if the price is about 100-110€ shipped.

Looking for Model F AT in Europe. Let me know if you have one you are willing to part with. I know there are some available in US, but i feel like shipping and customs are bit much for my wallet.

How much does something like that cost? I'm also wondering because I couldn't seem to get any conductivity from the wire, even in a section that isn't broken or scratched away. Is there some mask or something that has to be removed first? Couple of € from aliexpress or other usual suspects, more fr...

I would use something like "Copper Foil Tape with Conductive Adhesive" from adafruit or equivalent, cut into appropriate shape. Or barring that, regular copper foil with small dabs of conductive paint where copper meets the membrane trace, as regular foil doesn't have conductive adhesive.
