No that is not it the one I used was a full length controller, but
unlike the RT controller that was pictured it did not have an IBM square

don't recall any more.? By the time I left the Toronto Lab where I had
almost all my exposure to RTs I was already using SCSI disks in my PC.

I do seem recall using ESDI drives in a PC with
16 bit ISA slots but
it is a long time ago but I am not sure if the controller used was
the RT controller you have pictured, it seems to me the one used was
a Western Digital controller.
The most likely ISA ESDI would be the WD1007 controller.
There were a few variant submodels of that, such as with/without
floppy support, w/wo BIOS ROM.

Mine had the ROM.? On one machine, I had a 200M 3.5" drive.? My first
drive of that size of both capacity and physical size.
I think that I know where it is.
