The recently acquired a Memorex Telex IDE ISA controller (early 1990s), number 711186669587 , that has an unpopulated floppy / tape controller area on the board. The board has 34-pin internal header and DC-37 for external drive.
I would like to populate those missing components on the PC board. I could reverse engineer the design, and “fill in blanks” of the likely floppy/tape controller. The PLCC package (44-pin) is likely a late model chipset (tape/floppy). A schematic, parts list, or manual would shorten the effort for this board. Greg chicago
