The control store
was just the top 16 KB of main core memory! To change emulators,

a card deck!
Yes, a neat little machine, not at all like the brain-dead model 20.
Too bad that it came along much later--it would have been fun to fool with.
For sure! The 360/30 was an 8 BIT machine, 8-bit memory,
8-bit data paths, etc. Really hobbled the performance, and
restricted the peripherals that could be attached. The
models /22 and /25 had 16-bit memory and data paths.
