Sounds impressive...save for in 1987 the VAX11/780 was 9 years out of widespread use!! By 1987 the microVAX had been
around
for a
while,
the midrange VAX was 4x-8x faster than the 780 and easily 1/3
the size!
Cromemco was pretty neat but first, fastest not hardly.

The 11/780 may have been in decline by 1987... but out of
widespread use isn't true.
A large number of 11/780's were still being used in commercial
locations (although many had been upgraded to 11/780-5's -- non
FCC'd 11/785's)... but many were still in commercial use after
the scientific number cruncher types moved from the 11/780 to
newer faster and smaller boxes or to bigger boxes like the 8650.
There were many 11/780's still in use through the late 80's at
various sites... many outside the US. Saying the 11/780 was out
of widespread use in '87 is like saying the 11/70 was out of
widespread use in 85. Not true if you ever were in AT&T, or any
ex-Bell Operating Company -- they were buying 11/70's through
1984 or so from DEC as refurbs.
