- A friend of mine gave me the following list of pin assignments for
- connecting an
- external hard disk to his computer. He couldn't exactly describe what computer
- type it is (XT or AT), but only that it is a PC manufactured by Schneider. From
- somewhere he had heard that it should only be possible to connect a hard disk
- with a capacity of 20 MB.

- My question: Who can recognize simply from the pin assignment shown below which
- type of hard disk it could be (it can't be an IDE-Interface
- [= AT-Bus], because this should have 16 DATA lines)?
- So possible is only ST506 (MFM), SCSI, ESDI or Schneider-special.
