Does anyone make a PCI Bus ESDI disk controller?
Doesn't have to be 64-bit, 66MHz or PCI-X...:-)

I really doubt it. Wasn't ESDI basically dead by the time that PCI
came out? For that matter, how many ISA controllers exist? I kind
of think that MCA would be your best bet.

ISA ESDI controllers shouldn't be hard to find; EISA and VLB ESDI
controllers also existed. But I can't say that I've seen a PCI version.

It might be a good idea to look for a PCI->ISA bridge box and an ISA card.

Western Digital manufactured a 16 bit ISA ESDI controller. It was used
in the Apollo Domain 3K, 4K and 5K nodes as well, but with ROMs for
motorola 68K based systems. If my memory is correct, the ROM for x86
systems had the disk formatting utility at the usual place, C800,
offset 5.

I have an ISA ESDI, with a 100M 3.5" drive. (not ready to part with it
yet)
Weren't the WD -7 boards also ESDI?

Yup--they came in two versions even--an older 3/4 length model and a newer
1/2 length one. DTC also had them--and probably a host of other
manufacturers. At one time, they were viewed as the high-priced spread of
PC hard disks.
