I have a 386DX-33 computer with an interesting motherboard. It has an ISA-like slot under the RAM slots, but otherwise just looks like a normal 386 board: AT keyboard connector, sockets only for a 386 and 387 (no 486 socket), 8 RAM slots. The board has a sticker saying "TM 34" with presumably some kind of production number, and a stamping saying "VIP M318P1 TAM/33-P1", and when you boot the machine there's a line saying "AUVA TAM/33". Any idea what this board is, and what that slot does? I've heard those are for some kind of RAM expansion.
