I don't know how much to believe any more. But there are some folk here
who know enough to maybe be able to tell me whether it's POSSIBLE, . . .

A story that I heard:
A certain local community college a couple of decades ago had an 11/70
that they NEVER could get right. Constant problems; replacements of
entire drive assemblies, etc. Finally, the last straw was when the
machine went down (hard drive failure) for most of a semester, taking out
the COBOL classes, etc. that depended on it. The DP department decided to
sell it and buy PCs. That way, anything that went wrong couldn't take out
the whole lab at once.

They sold it to a certain local school district (which recently changed
their name due to bad public image!).

When the school district was ready to hook it up, they found out (after
the fact) that the electric company installers didn't understand the
difference between Y and Delta three phase! (I personally encountered
the same mistake when starting up a garage).

The electric company agreed to provide complete replacement of the entire
machine IFF those present would go along with a face-saving story
that the machine had been hit by lightning.

The community college got their PCs (most of which are still around) and the
school district got a replacement machine that worked reliably.


Lightning is rare around here. Which story should I believe?
