Any ideas from 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.
Does the card work in Applesoft with the PR#3 command? If yes, make sure that you have CP/M 2.23 or newer, since 2.23 (also known as 60K CP/M) works with a lot more different cards than 2.2 ("56K CP/M"). I'm talking about Softcard CP/M here, other Apple CP/Ms might have different version numbering.
