Hi,
All address lines on the RAM, near the CPU are high (5V). So I guess one of those two is defective.
Decided I'll sell the parts.
A few final questions:
Can the (E)PROMs be used in a KN-3000? Can the hard drive be used in a KN-3000 (does it have the same connectors on the CPU board)?
Is the display compatible with other models?
Thanks again!
