QBus ESDI controllers are relatively cheap. I have several Emulex QD21, Dilog DQ696, and Sigma SDC-RQD11 QBus ESDI controllers. The problem I have with them is that I now have more controllers than working ESDI drives. Some of the drives that I had which were working have died while sitting idle. Guaranteed working ESDI drives don't seem to be cheap anywhere and shipping them isn't cheap either. To me it seems a lot more cost effective and less trouble in the long run to pay a little more for something like a CMD CQD-200/220 or Emulex UC07 SCSI controller. I've somehow managed to acquire a couple dozen or so QBus SCSI controllers of various flavors over the years. -Glen
