What seems to make the MassComp 500 fast is (a) a 4k cache on the cpu
board, (b) a high speed buss along-side the massbuss for fast
memory access. My guess would be that the cache makes all the
difference. The cpu chip itself is a 10mhz 68000, with a helper
68000 for paging.
The Unix seems to be a port, not a look-alike.
The benchmarks from Masscomp make it vax-750-like, depending on the
disk, etc. I wouldn't actually call this Vax-class since it is
well below a 780, but it considerably better than a Sun. I haven't
done my own benchmarks, however.
They ARE shipping--around 100 machines are out there, if I remember
right, including two right in my neighborhood. Don't have
one myself yet, but I'm talking to them.
I am very impressed by the packaging and hardware design of these folks.
Their software seems solid as well, but I haven't looked at the code.
The software people I have talked to knew their stuff. I consider
the prices to be Sun competitive, and a lot better than a vax 750
if the benchmarks old up.
They have a local sales organization in many areas, call them up
and ask for information. Tell them Mark Weiser at the U. of Maryland
sent you.
