J1mbo updated his XT-CF adaptation of our XT-IDE CPLD board. You can check out his wiki page with all the details about the board, the BOM, and the source files. This board allows vintage XT computers to use CF cards as hard drives, which keeps lots of old industrial and medical equipment going using modern parts.
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.
