The headline would be UNIX crashes IBM system.

It seems that we had obtained an UNIX system and was using it for
the first time.  In those days UNIX was brand new and the rest of
the world had never heard of it.

Any rate, we had attached our PDP-11/45 to an IBM 370-155 system
running JESS-2.  This meant the PDP-11 pretended to be a RJE
card-reader/printer/punch station.  Things were going quite well
and the Bell Labs software worked great.

Then one day we found that our rje line was disconnected and the
IBM people refused to allow us to talk with the IBM machines.
The reason, they claimed, was that most of the time that UNIX
submitted an RJE job the IBM would promptly crash with no error
report.

Finally it was determined that when the IBM people had sysgen'd
the line they claimed it was a 2780 with a 80 character line and
we were a 2770 with a 132 character line.  This didn't cause
problems unless our line and the next adjacent line both
sumbitted jobs at once.

But I thought it amusing that DEC equipment could crash an IBM
system at will.
