The UMR 360/50 was one of the first owned 360s. They were given a
360/40 because IBM could not deliver the 50 on schedule. I don't know
how that was handled.
The 50 at UMR was also odd because it was a 512K main memory machine,
and 1mb of LCS, giving a non power of 2 memory size. Supposedly lead to
some bug fixes.
Ran HASP and MVT 21, as well as CPS
