For sure! The 360/30 was an 8 BIT machine, 8-bit

memory and data paths.
Do you mean the 360/20? On the topic, were the 20 and 40 the only
members of System 360 to use TROS?
I remember picking up the programming manual for a Model 20 and
realizing that I'd essentially have to re-learn programming. 16 bit
registers, stripped-down instruction set, no I/O channels, "substitute"
instructions for regular 360 fare.
A really strange thing was that the 1130 came out *after* the 360/20.
