Looking for a WD 1001 55 Disk controller

Sounds similar to the one I've got; it does have provision for four
data cables, but only two have connectors installed. So what does
this 40 pin host connector connect to?

And what happened to the person who started this thread? Was he
looking for a chip or a board?

The WD 1001-55 (the "BIG" version) had four data cable connectors, IIRC. In
fact, it didn't look very different from the 1000-55 at all. Both of those
boards used the 8X300/305 (depending on version) and the WD1100 chipset. I
had the datasheet for that board in my hands less than two hours ago, but
don't now remember where ... <sigh> another senior moment, I guess. The
small versions (1000-05, etc) used the WD1010 chip and a couple of others.
They do seem to be pretty much interchangeable, though. My own WD 1000-55
board had a 50-pin connector rather than a 40-pin host connector. The extra
signals were just ground and power, though. The ones I've kept only have the
40-pin host connector, which makes them all compatible at the interface.
