Re: http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&item=2034559690 (Ebay auction of Heath H-89) If you look at the last picture in the listing, it show a board that is mounted on top of the CRT. The same picture clearly shows the mounting screws for both the terminal board + the CPU board, so this has to be some sort of an aftermarket board. My thinking is it is some third-party graphics board. I just wonder if anyone else has any ideas about this.
