Condition
Consists of the base kit (processor board + keyboard/display board). An additional (hand wire wrapped) memory expansion board connected through an EXORciser backplane to the processor board.
Generally seems to work, the monitor program is usable.
There seems to be no RAM at the normal addresses (0000 - 00ff). Trying to change memory doesn't work there. Perhaps it is mapped elsewhere. The JBUG scratch RAM at a000 - a07f is working.
Since I don't find any RAM, I was unable to actually enter and run a program.
Some chips were added on the free space of the processor board, but three wires are loose. I don't know where they should go and it requires soldering on the processor board.
I tested using a PC ATX power supply to provide 5V to the EXORciser backplane.
