360/50 is a 32-bit machine, the real thing has a core memory
"local store" and (3, IIRC) built-in channels. it does not
allow memory interleaving.
The 360/65 has a 64-bit path to memory, and does permit
interleaving. it also allows two /65s to be put together in
a multiprocessor system. There are a few additional
instructions to communicate between CPUs. The 65 has solid
state local store, and a 56-bit ALU, so it can do
double-precision floating-point arithmetic without having to
double up the cycles, as the /50 does. The /65 has no
