Anyone build a version for a 122 key Model-M (20+8 pin flexcable)

[larsberntrop]

I lucked into a 122 Model-M Battleship previously attached to an IBM 5250 terminal. I like the ctrl-M, but I have different flex cables: 20 + 8. Did you ever come across such a setup? is there a version of ctrl-M for 122-key?

Hi Yes, the ctrl-M does NOT support the IBM 122 terminal variant (aka battleship). This was decided in favor of simplicity, cost and support for the later Lexmark models with the smaller PCB. There are other ways to modernize your IBM 122 keyboard: - BLUSB controller with forked QMK: https://www.ebay.de/itm/156518694401 - Model X controller with ZMK: https://www.ebay.de/itm/276766848419 - DIY based on Blackpill with QMK: https://github.com/qmk/qmk_firmware/tree/master/keyboards/ibm/model_m_122/m122_3270 All the best, Am Fri, 31 Jan 2025 11:59:57 -0800 schrieb Lars Berntrop-Bos ***@***.***>:
