I figured it was some sort of stiff sidewall. Must be a real b**ch to
install and remove from the rims. I know what it's like to deal with
mounting 6-ply sidewall tires used on small commercial vehicles not having
split rims.

Pressure monitor? How does the driver get that feedback? Obviously there
would need to be information sent to the driver as to pressure failure.

I do not know for sure if there was an IBM 1103 (anybody?) but for sure
there was an 1130 (I'm not _that_ old ;). Yeah, imagine the confusion when
throwing around 1103, 11/03 and 1130 numbers during a discussion or
whatever especially with non-technical persons.

ISTR the same. There was a panel across the back of the desk-like cabinet
with switches/lights and a Selectric typewriter set in the center as the
local system programming I/O. I vaguely recall one day the IBM CE was in to
do maintenance/repairs and the door at the right side of the 'desk' was
open to show off the 32k core memory area.
