I have a highly original late production XT, with the 640k system board,
720k hh floppy, 360k hh floppy, and full height IBM 20mb hard drive.
Interesting features include a Y cable to power both floppy drives from
the PSU connector (Y cable has black wires, and a cloth tag with IBM
part number 6480173). Also, the 720k drive has a plain blue eject
button. The 3.5" drives from the PS/2 series were labelled 1.44m or
2.88m as appropriate.
Yes, that sounds exactly like the drive in this machine.
The 360k drive has an asterisk on it, just like
on the optional AT 360k drive. Apparently the IBM
convention for 5.25"
drives was that if it was a full height floppy, drive then it was 360k,
if it was a half height drive it was assumed to be 1.2M, unless it had
an asterisk, then it was 360k.
This 360K drive only has IBM marked on it. But I have seen a number of external drives
with the asterisk on them. The X drives for the IBM P70s all seem to be marked that way.
Thanks for the info.
