another RISC question

[budd at arizona.UUCP]

regarding RISC's.  I am probably showing my ignorance (not unusual), as
the only information I have on RISC is the article in COMPUTER a few years
back (Sept 82, i think).  Anyway - my question is whether this thing
is designed to be a single user machine only, and if not isn't context
switching with all those registers somewhat expensive?

Same question can be asked about the pyramid machine.
