View Full Version : Heathkit H-8 with Hex keyboard

January 5th, 2014, 01:27 PM
Has any one ever seen one of these? Supposedly the keyboard overlay's were supplied with the H8-6 Z-80 board to allow Hex input. Now in the instruction manual for the H-8 you enter programs in Octal mode. Does this still apply with the Z-80 board in the unit? The Z-80 is supposed to be backward compatible with the 8080. Just wondering if anyone has dealt with this before. Mgarlanger you around? :confused:
