I seem to recall that reworking the 360/30
microprogramming was preferred by tinkerers over the
360/40 was primarily that CROS was easier to work with
than TROS. I don't recall what the RCA Spectrolas used.
And the 360/25 had all
writeable control store. The control
store was just the top 16 KB of main core memory! To change
emulators, restore from a microprogram crash, etc. you
loaded the emulator from a card deck!
