The PS/2 keyboard interface is "just" a start bit, 8 data bits, odd parity, and a stop bit, with each bit synchronized to a clock signal.
but I think that's going to be a lot of work. If you're not averse to building some hardware and possibly writing a driver of your own, you might be able to make something work. Software wise, it would be (?) a question of loading the now blacklisted PS/2 module in my Linux Devuan installation.
Ie: I'd avoid converting PS/2 to USB and solve the current draw issue some PS/2 keyboards have and free a USB port. Would it be possible to wire the PS/2 Model M with a DB9 plug and directly use my workstation's serial port, like it was possible with the PS/2 mouse? and the PS/2 -> DB9 adaptor has this pinout: Since my Sun Ultra 24 workstation has an on-board RS232 which at some time in the past I enabled in BIOS and properly set up to use my serial data-logging hardware. I think it was original issue with the early Microsoft Serial Mouse 2.0 which had a PS/2 plug.Ī USB Prolific PL2303 Serial Port board (invaluable)Įventually cannibalised from it's original junction box and hard wired into my Palm III's sync base so as to make it USB instead of serial. crack open the above converter, hard wire it to the existing controller inside the keyboard case and wire in a nice USB cable with or without a socket.īut while looking through the collection of things I have stubbornly refused to throw away every year, I came across two things which at different times held permanent residence in my sack along with the rest of my gear:.replace the original cable with a new one and use an active PS/2 -> USB converter.Once cleaned up and checked out, my guess is the two easiest/least $$$ choices would be:
(Yes, I checked the model number, it's PS/2). It seems those flat cables were not very sturdy. I'm currently awaiting for dispatch/delivery of a 1995 PS/2 Model M keyboard w/attached flat cable but a missing PS/2 plug
