The Toshiba 5200 Expansion Unit provides 5 extra 8 bit slots. Plugging
the PC-36 or PC-02 gets some response from external drives, but when
it comes to WRITE operations or restore, the units just hang. There
arer NO other cards in the expansion box so it can't be an IRQ or
other conflict. The cards are set at 300Hex, IRQ3 (tried 6 and 7) and
DMA 2 or 3. It makes no diffrence.

Does anyone have any suggestions as to why a DESKTOP 386/20 presents
no problems but the Toshiba 5200 and expansion unit does? The only
things I can change on the interface is whether or not pull up
resisters are on the DRQ lines or not and the bus speed being 4.77 fixed
or the speed of the 5200. It's currently on speed of the 5200 bus.
