Some things to check if the system is not working:
1.
Two ZT 8809A frontplane connectors accept the ZT 90014
serial cable. STD ROM works only in serial port 1 at J1.
2.
If a PC is used that has more than one 25-pin male
connector, be sure the serial cable is plugged into COM1.
3.
Check to see the EPROM and RAM chips are installed in
the proper sockets. EPROM should be installed in socket
5D1. RAM should be installed in socket 7D1.
4.
Check pin 1 orientation of the installed EPROM and
RAM(s). Pin 1 should be to the left, with the board
oriented component side up, goldfingers to the left. If a
chip has a smaller number of pins than its associated
socket, it should be right-justified in the socket.
5.
Re-verify the jumpers, particularly those associated with
the socket and memory configurations (W40-W45, W49,
and W55-W59).
