The Lisa is a newer model and has an integrated ProFile above the drive. The floppy drive looks similar to another tested good Lisa floppy drive I have from an earlier model (dated dec 1983) but that drive has a daughter board next to it in it's own Lisa and doesn't seem to work as a replacement (seemed to exhibit random activity) in the newer one. I've also tried a more modern 800k drive which also didn't work (same issue). FInally I tired a 400k drive from a 512k Mac from approx the same era but same issue there. Can anybody provide me with guidance on which kinds of Floppy Drive should work so I can determine if the issue is with drive compatibility or possibly an issue on the I/O board? >> >>>> Many thanks, >>>> Geoff >> >>>> On Mar 23, 2011, at 2:46 AM, Diogenes45 wrote: >> >>>>> I have just examined the 400 KB disk drive: Many of the sub miniature >>>>> caps are dried-out (I have a special capacitor tester) - the signal >>>>> from the PCB to the R/W heads and vice versa is very weak and >>>>> distorted. >>>>> I think it's futile to exchange all caps on the board... the best >>>>> solution would be a replacement drive (or original Sony controller >>>>> board) or even better: an upgrade to a 800KB drive. >> >>>>> Helmut >> >>>>> On 22 Mrz., 22:56, "Terry Stewart" <te..._at_email.domain.hidden> wrote: >>>>>> Helmut, >> >>>>>> I do have two non-working drives which aren't worth much to me.
