This board requires a Z80A CPU, perhaps your Z80 pod CPU is too slow? 
Try installing a Z80A in the pod (I run a Z80B)...

I do know that with pin 8 of RP4 cut and the board side tied high, 
that I can run the RAM, ROM and I/O tests successfully on an OR that 
is STILL on my bench. Flacky problems were caused by a bad ground 
connection to a buffer.
