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, etc. Live and learn! :-) Noel
