Commodore PC-20-III

 I have one but haven't had it out for several years. Ray Carlsen had a PC10
and posted some stuff about it on cscbm. I used a Commodore1402 monitor
with it that I had acquired at a different time and IIRC later my Tandy CM-5
RGBI monitor. Jim Brain's list catalogues the 1402 as a Hercules ( In the
monitor or on the motherboard of the PC20 ?).

 I'm wondering if you have a different model. Mine is labelled "PC10C /
PC20C" . The PC10s and 20s were virtually identical I believe except for
configuration. Mine has no cards and with 2 slots missing cover plates. It
also has a sticker saying "ATI 2400 modem installed" but no modem.

 All the ports are labeled. It has a 9pin "Mouse" port, a f-db25 "parallel port",
m-db25 "serial port", "comp video" RCA port, 9pin "RGBI", and 4sw. "config"
block with 3 possible configurations. "Color40", Color80", and "Monochrome".
 Possibly yours is an earlier model. If you like I can send you my switch
setting list later.

 However I am about to embarque on a trip west to Vancouver and won't be
back for about 3 weeks.

 Still haven't found the pinouts for the Commie L-T 386. Guess I'll have to
probe it.
