J1mbo designed a PC/XT to Compact Flash adapter. This board gives vintage XT PCs, often found in industrial and medical systems, the ability to use Flash cards as hard drives. It’s loosely based on our XT to IDE hard drive CPLD board, which is itself a CPLD-based knock off of the Vintage Computer Forum’s XTIDE board. J1mbo’s version uses a flash card holder instead of an IDE hard drive.
