While waiting for the new PCBs to arrive, I’ve been working on the PS/2 RS232 to ASCII keyboard adapter manual. Currently at 14 pages, this manual seems quite long for a device with 2 chips, some connectors and a few capacitors.
I just posted a preliminary draft of it here – Since I don’t yet have production boards to test, assume that the manual may have errors, but it will give you an idea of the capabilities of the device.
