The IBM PS/2 family supported them all, ST506, ESDI and SCSI...

Being that I have all the IBM PS/2 FE service documents, a quick
look at just the Model 80 option list gives me:

90X9063 Fixed Disk Drive Adapter (ESDI)
72X8540 Fixed Disk Drive Adapter (ST506)
15F6779 SCSI Adapter/A With Cache

I probably also have at least 1 of each of these cards around here...
