Where might I find schematics for the DataFlyer Plus and DataFlyer RAM boards. Also a copy of the ROM/PLD chips.
I am guessing no where,since this was a commercial board and no schematics were released for it(that i know of). PLD code was also usually not released.
Only chance may be to track down the author of the hardware and hope he is nice and kept all this from 20~ years ago. Another possibility is find another working board and hope the PLD wasnt protected(hah).
