Not applicaable to your problem, but somwhere I have
the manual for a
Fujitsu Eagle. It contains full schematics and block diagrams of the
ASICs. I have a simialr manual for an 8" SMD drive, I think that may well
be Fujitsu too, I would have to check.
Yep, the manuals are on bitsavers. Last year I had to repair a failed 8"
SMD drive (M2322K), it wouldn't seek to the correct track and hence would
fail spin-up diagnostics. Thanks to the very detailed schematics and
functional description I was able to locate the failed component (opamp?
gate? I don't know) on the r/w/servo control board.
