}Well, the problem may be that some time before the SE and II came

All true, but it was a stupid excuse your dealer gave you.

My upgraded to 512ke internal drive failed. I got a replacement drive,
which didn't work, called my dealer, he said, "You must have an early
drive, the cable to the drive changed. Bring your cable in.".

I brought my cable in, the tech person took it into the back room, and
clipped one lead. The drive works fine. My memory of exactly what
he did to my cable may be wrong, i.e. he may have clipped two wires
or something, but the point is, it took 2 minutes for him to change,
and he returned my same cable to me.

I suppose I could always pull my case apart and find out 8^)
