Nope, not on a model 20. The 360/20 did not have channels,
it had specific I/O controllers built into the CPU backplane
for disk, tape, cards and printers, and an optional one-line
So, all peripherals plugged into their specific controller
in the /20, there were no external control units like a
2821, 2803, 2314, etc.
The 360/20 was a VERY limited machine, max of 32KB of
memory, but most had a LOT less.
There was RPG for it, but most were used for off-line
spooling of cards and printing, or RJE systems.
If there is a 370 there, possibly there could be control
units for that machine in the collection.
