Re: More about the Widget Problem

    Actually, the problem is that I don't think the drive controller and the Lisa are talking on a normal basis. Only one or two of the many times I've tried to boot have been successful in getting any sort of error message. The rest of the times, the machine acts as if it's a Lisa without a hard drive at all, other than the fact that it hangs for a minute or two before trying to boot from a flopp and getting the Continue, Startup From menu.

    I don't believe I have heard the brake clack, the only noise is the drive spinning up and the motor running, but no seeking occurs AT ALL. The light doesn't flash, and there appears to be no head activity, which leads me to believe there is something weird going on with the Widget Controller card(s) that it isn't even trying to talk to the drive, or to the machine, or both. That is why I am so confused, as it is usually non-working, but a few times it has talked to the drive and gotten various errors, so I'm not sure if there is an intermittant part or maybe I should disassemble the controller boards, and clean all contacts and IC sockets? It is almost impossible for an IC to cause such an intermittant issue, and at first glance I didn't see any electrolytic caps on the boards, so that probably isn't the issue either.
