External TBC for Toaster 4000 system?

[Jeff]

Any old PC motherboard with ISA slots will work to power the DPS TBC. The ISA connector just needs to supply power to the card. The control is done with the serial cable to the Amiga (or another PC). I have 2 DPS expansion cases, one holds (2) cards and the other holds 8 or 12 I think. The backplanes are passive in both cases and supply power only. The DPS cards are cheap these days and work quite well.

You can see an example of the 2 slot case in this picture right under the VCR.

The case is a DPS ES-2200. It has two passive ISA slots and front panel controls. You can find them on Ebay now and then for a pretty reasonable price, sometimes even with a TBC or two already installed. That's where I got mine. You can also put a DPS Vectorscope in the second slot.
