Hi
One should note that double termination can also cause flaky
operation as well. I've seen it twice now that I have a machine
that has a flaky disk and I open it up and see a terminator
on both drives. Removing one brings back normal operation.
One of the machines was a KayPro and the other was my Olivetti
M20. I suspect that these were that way from the beginning since
both normally ship as dual drive machines.
