  I think you may struggle. Looking at the early 6800 Journal there are many boards, which can use Gimix “Ghost” addressing and are supported by the GMXBug includes the driver software.


volume 1 n 5 Page 3 (P5 in the PDF) has a Gimix advert. There is a GMBBUG 02 manual on the flex user group site, but it stops at the chapter before the screen i/o routines….

No.. mine has a 2513 character generator.. the one in the ad uses ram based character generation.  Based on IC dates my board looks like mid to late 70s.. a fair bit earlier than that one.
