Me, too... mine came with a board loaded with EPROMs mounted _under_ the
AIM-65 motherboard.
Oh... a little tip - I have proven that the 6520 on the display board can
be replaced with an 6821 (I have a number of 6821s since they were used to
drive the printer port and the diagnostic display for the original COMBOARD
model).
I have more than one AIM-65 at home, but only one display board. One of my
projects is to fabricate a replica on perfboard. Mostly via eBay, I've
managed to pick up a few of the 4-char ASCII displays that are on that board.
Barring that, I was thinking about using some modern ASCII displays that I
picked up for a couple $$ each from BG Micro, and re-writing the relevant
ROM code. Obviously, direct replacement is simpler.
