If this helps...

My version 03 IIc with my CT100c hard drive, 1mb Ram IIc memory card, 2
UniDisks and an external 5.25" drive maps out with Slot Scan as such:

s6d1 - internal 5.25
s6d2 - external 5.25
s5d1 - CT1 (1st partition of 100mb hd)
s5d2 - CT2 (2nd partition of 100mb hd)
s4d1 - ? (it just renders a question mark)
s4d2 - ? (same thing as above)
s3d1 - UniDisk #2
s3d2 - /RAM Disk
s2d1 - CT3 (3rd partition of 100mb hd)
s2d2 - UniDisk #1

The assignment of slots jumps to slot 2 aft3er slot 5 and works its way
up from there.
