Copyright 1980 John Bell with a 6502 processor.
6502 CPU
6522 VIA
74LS10n
2 x 2114L
6 resistors
6 caps Two special
24 pin gold plated low insertion force socket
2 x 25 Pin edge connector.
John had a lot of boards.
All his schematics were in his catalog, if I run across it ...
Be sure and consider the 6522 VIA, it is a superior chip compared with the 6820.
