The hires card uses the thomson ef series vdp chips. There are several variations which have different resolutions from 512*256, 512*512, to 1024*512. These are strictly bitmap mode chips so no need to modify the screen editor code. Output will be to a separate monitor.

There is I read for the 8032 color that never launched a 32K Screen Edit ROM. Works with BASIC 4 and if this ROM exists may be convertable to be used in the CBM-II > bReceived on 2018-06-25 16:00:37
