IDing IBM Floppy Drive Parts

Hello, all: I got a couple of IBM-labeled Tandon drives and a MPI/Control Data drive. The Tandon drive is a standard TM100-2A and the CD drive has the following ID#s -- Part 77711801, IBM Part# 1502060. I'm trying to recycle these in my N* (double density setup). The jumper area is unlabeled on these drives, as is the terminator spot. On the Tandon drive, I found a TRW IC near the floppy connector...it has a designation "516-3-151G"...this seems to be the terminator. Can anyone confirm the placement of the terminator and the jumper block pinout for both drives? Any help appreciated.
