You need the following:
1. A high enough version of the EPROM
2. A PAL Fuse Map for burning a PAL that will allow the board to act as a QDT controller
(Disk and Tape)
3. A special cable that allows you to connect a Serial Terminal
4. Instructions on how to get into the hidden menu to configure the board
I should have #4, but I have no clue as to where it is. The person I knew that had #2
lost that data in a fire years ago. I seem to recall hearing about someone jury-rigging
#3, I used the proper cable and bulkhead plate.
If you burned your own PAL yourself and you didn't secure the PAL (or
does a PAL16L8 even have a security fuse?) then even if the known PAL
Fuse Map was lost I would assume that it could just be read back from
the PALs on the boards you have, along with dumping the firmware
EPROMs as well.
