use them with CP/M.
OK, right...
I asusme the interface was little more than a level shifter, and that the
serial ouptu was bit-banged on the TRS-80. Dos anyone have shcemaitcs
and/or the drivers still?
Yep.. I still have my printed catalogue of CX
printers, parts, options,
etc for The PrinterWorks :-)
A wonderful book. Also their SX book.
I nevver saw the SX one
Bob Davis (may he rest in peace :-() very kindly sent me the CX one. But
alas _after_ I had rebuilt my first CX (it started off an a Canon LBP8A1,
the formatter board failed, so after a lot of probing around, taking things
apart, and looking at the logic analyser, I turned it into a CX-VDO, put
the approriate chips on my PERQ's OIO card and got it working. No, not
first time, I'd missed off a jumper wire on the OIO board, which mean the
FIFO output regester didn't reload).
It's a great pity I didn't have it earlie. It wou;ld ahve explained the
CX-VDO cabling, I could also have ordered some replacement parts that I
had to make from scratch,
