After putting two and two together, I knew the Widget had a controller
board problem somewhere. From inspecting and cleaning the other boards in
the Lisa, I discovered that Apple had used the cheaper style of IC sockets
on the boards, stamped vs machined contacts. The machined sockets don't
seem to hold up as well over time, so I figured I'd do what I normally do in
desperation, reseat ICs in order to clean the pins. I must have done
something right, as the next boot, the Widget fired up to life, the brake
clacked, and the Lisa began to boot!!! I am gathering that one of the
EPROMs must have not been making contact with the socket, thus the
controller board wasn't running at all, and the Lisa would rarely see the
Widget, if at all. I would certainly suggest trying to reseat all socketed
IC's on any controller boards before throwing in the towel on a drive.
I'm curious to know now, though. What are normal Widget sounds? I'm
not used to drives of this vintage, so I don't know if an occasional
chirp-like sound (rapid movement of R/W head motors?) is normal.
Additionally, is there a benchmark to see if the drive is working optimally?
How long do things like the calculator, for instance, take to be loaded?
I've never had the pleasure of working with a Lisa before, so I don't know
what to expect.
Thanks,
Chris
