All right, so here's the first few Pro related
questions:
1. I don't have a keyboard or monitor to go with it. I see from the
manual on Bitsavers that the monitor gets a composite video signal,
and that the keyboard uses 4800-baud 8-N-1 RS423 signalling. Is the
protocol described anywhere?
It's a plain LK201 keyboard, asused on VT220s, VT3xxs, etc. Are you sure
there's no one somwhere in all thac collection.
I am pretty sure I have a document giving the keyboard protocol if yoy
need it.
The monitor is a RS170 (US TV rate) composite one. Or RS170 RGB,
sync-on-green if you have the 'extended bitmap option' and want to do
colour (a mono moitor works fine with the extended bitmap option, you
just get a greyscale, not colour). I am pretty sure pinouts of the DA15
keyboard/video connector are in the mnauls on bitsavers, or search the
archives of this list for my 'universal rainbow monitor cable'. It's much
the same.
