Dead AIM 65??

: I think I have heard of the AIM 65/40... if someone here knows such : things, was the motherboard re-engineered? Is it possible to retrofit : the 40-col display to the original AIM? Also, was the 40-col VFD run : by something like an HD44780 chipset, or was it some kind of raw : interface? These days, 40x1 or 40x2 VFDs based on the HD44780 are not : difficult to locate and are not all that expensive. They are also :trivial to send chars to. : -ethan The AIM 65/40 was quite different from the original AIM 65, it was really useable as a fairly powerful, though inexpensive 6502 development system. I never used one as I left consulting in 1980, but I did see one, and it appeared to be a pretty good computer. More details can be found at: http://oldcomputers.net/AIM-65-40.html which has info on the AIM 65/40 (which came in several models) and a Rockwell Design Center (which I never used) and System 65, which I did use and thought it was a very capable development system. As you can see, the AIM65/40 is a completely new board, I don't know if one could use the 40 Char display on a normal AIM 65, but I suppose you could, you would just need to write new driver software for it, maybe replace the AIM 65 ROMS with EPROMS with most of the AIM 65 OS and new drivers for the display. Could be an interesting Project, but it could compromise an otherwise vintage computer (the AIM 65) in the process. IHTH, AndyD
