⚓ State
It doesn’t seems to start, nothing on the serial port.
Tried with another RAM IC and same for the serial IC, nothing, CPU READY pin is high, reset doesn’t seems to be held.
The front panel doesn’t do anything if the connector is unplugged.
There might be two missing eproms or the order has been messed with.
