Any ideas from you Apple experts how I tell CP/M software
to use an 80 column card? Display is 40 col from motherboard,
all I get from 80 col card is a blinking cursor.

No switches or id on 80 col card; it has 3 EPROM sockets,
but only ROM2 & ROM3 are present. No reason why ROM1 should
have been removed, so I'm hoping it was an option.

Both video outputs and the built-in RF out all use RCA
connectors, BTW :)

And in reply to the question about SO239 (AKA UHF or 83 Series)
connectors for video, the commercial (as opposed to homebrew)
video out adapter on my PET uses one; other than that, in my
experience the mass-produced systems used either RCA or
proprietary connectors, and S100 & similar multi-card chassis
used BNCs when they had internal video.
