Specifically, the plug and socket at each end.
This is a board-to-board cable from a 1989-era Toshiba laptop, which connects a dedicated modem port to the modem itself (not present in my laptop). The pinout is a very cut-down ISA bus with only a few address lines, and looks eminently suitable for hacking --- if I can find a plug which will go into the motherboard connector (I'd rather not destroy this one). But for that, I need to know what it is; the cable markings are no help. (I'm hoping to find an IDC variant.) What is it?
