KIM-1 - Wrong resistor values #99

Closed eduardocasino closed 2 years ago

eduardocasino commented 2 years ago

R18 to R23 pull-ups should be 1K and R41 to R46 should be 100R. They are also swapped in the original schematic and parts list. Checked against photos of multiple systems and also inferred from the schematic or the transistors would be permanently switched on ;)

@nandgate can you look at this concern?
