Huh, I never knew about that. (The manuals don't mention it.)
I was just last night looking at the microccode for the 11/04 (a very similar
machine - they share the front consoles, etc), and it doesn't have anything
like that (see the /04 power on ucode at pg. 130 of EK-KD11D-TM-PRE).
Looking through that /34 ucode flow diagram, I discovered that the /34
supported the M[FT]PS instuctions - I thought that was only the QBUS CPU's,
Live and learn! :-)
