RT keyboard protocol wanted
Ignatios Souvatzis
I'm reviving an IBM 6150, and found that the keyboard is no longer
where I got the other parts of the machine. On the 'net, I've found
instructions on how to use the RT keyboard with an AT (mostly cable
spicing and a script using xmodmap to remap two dozen keys); but as
far as I've read, it wouldn't work in the other direction as the
6150 uses commands in its keyboard test sequence that aren't implemented
on AT keyboards. Is this true?
Are the RT keyboard commands publicly documented anywhere?
(Microcontrollers are cheap nowadays...)

Wish I had that document. Thanks, anyway.
