The *shell* seems to be from a IBM 2.1GB drive; the drive that normally
works in this shell in my 760E is a 6.4GB drive (Toshiba?), though. If
I understand this correct, I shouldn't need a different setup when
switching between a 6.4GB and a 1.6GB drive, correct ? Strange...
Anyway, in the other laptop, the Fujitsu 1.6GB disk works when all
jumpers are removed (i.e. 47-48 open).
I guess I will make up my mind if, in the case of trouble, I'm able to
find a cheap replacement for the cable here in Germany, and then I will
go on and try to somehow unconnect the according pins ;-(, and hope for
the best ;-)
Thanks for the assistance,
Gregor
