I seem to
remember real world Unibus was mentioned to be up to
1-1.2 Megabytes/second so your number may be right. I often wondered
if it really got that high in real life...
Unibus runs to 7mb/sec...slow, yes, but not bad for the time it was designed
and [very widely] used, IMO. I rather like Unibus.

Thanks for that data, Dave.
Unibus, for it's time, was absolutely wonderful. Although a little quirky
(the closer you put a card in the cage to the processor, the higher
priority at that level? And funny Bus Grant continuity cards?), it did
serve as an easy-to-use and flexible I/O bus.
I do think that DEC had some wonderful computers, and I learned most of my
hardcore computer theory on 10s and 11s, and later, VAXes. Great Stuff.
But now obsolete.
But that's why we've all gathered here, right? ;-)
