Dwight, The connector blanks shown in the picture are factory standard of the later models, and they included a BLANK for 488. I agree, I don't think Heath ever made a card to implement it, buy my '89 has the 488 blank on it also. The only IO positions populated would indicate a 3-port Serial, and an extern floppy I/F of some sort (they supported 8" and Hard and Soft 5 1/4" of various densities. I remember seeing third party adds (in the day) for add-on graphics capabilities, but don't really remember how they were installed. ISTR that they were replacement boards for the terminal board, but I could be wrong. The reason I asked was, as a kid, I drooled over the ability to do pixel graphics on a CP/M machine. I wonder if this would be a cheap way to pick on up? Probably 0 documentation on it. Maybe I'll email him....
