Are you sure the drive is ESDI? I think the model 70 shipped with an
IDE drive.
The IBM PS/2 Hardware Interface TechRef contains a pinout of the hard
disk connector. The signals look to be almost a subset of the MCA
signals. It certainly doesn't look like an ESDI interface.
I guess you could call it 'IDE', but it's not the same interface as is
used on more normal PCs.
I think it could be considered "IDE" in the original sense - Integrating
the controller into the drive, but it is not ATA (AT-Attachment) IDE.
