Do you have ESDI drives that have been formatted with a Dilog DQ696, and you need a DQ696 to use the drives with their existing format, or would it be OK to low level format the drives and any QBus ESDI controller would work, such as an Emulex QD21, or a RQD11 from various vendors? Where are you located, and what is a QBus ESDI controller worth to you? Here's an Emulex QD21 for around $100 in the US: https://www.ebay.com/itm/372959317948 Does that exceed your budget, or wrong location, or not compatible with your needs? I probably have more Dilog DQ696, Emulex QD21, and SDC-RQD11-EC controllers than I do working ESDI drives. At one point I had several working ESDI drives that have now gone bad over time while not being used. It's been a while since I tried spinning up any of them to see if any still work.
