Looking for Tandon TM-100 service manual (w/schematics & waveforms)

I'm looking for Tandon TM100 service manual w/schematics; one of my TM-100-2 drives in an IBM 5150 here started acting up (stepper motor is stuck at track 40 and won't decrement) and I'm trying to find a useful service manual to debug it. The two tm100 documentation/service pdfs I've seen are a scan of a staple-removed 21 page or so packet (this scan is missing pages 8, 9, 12, and 13) which has no schematics and is missing some pages; The other is 7 pages scanned from part of a larger document (100 pages or so), which looks like it would be useful if I had the whole thing. Neither of them are particularly helpful. Does a scan of the larger tm100 service manual exist? Does anyone have a paper copy I could borrow/copy/etc? -- Jonathan Gevaryahu jgevaryahu(@t)hotmail(d0t)com jzg22(@t)drexel(d0t)edu
