I recently bought a DataFlyer 500 SCSI. I'd like to enable the IDE functionality of the board.
I've compared the SCSI-only version with the SCSI & IDE versions, and from what I can tell, I need to add:
(1) 244
(2) 245's
Couple odd resistors (pull-ups maybe? Haven't looked)
IDE Connector
DTACK PAL IC
Would the ROM be the same?
AFAIK, my only real concern would be the source for the DTACK PAL. If I had the equations, I could probably put together a CPLD to mimic it. Not sure where else I might get said PAL.
Has anyone attempted this before? or have additional information to help?
My end goal would be to use an IDE compact flash adapter and boot from that.
