ah
I see...and if the 780=a 780mhz processor...just overclock it
The "bad" news is that a VAX-11/780 has a 500KHz clock (I had to
check I didn't write 500MHz there :-)
Err... are you sure you don't mean 5 MHz? I know it was 1977 and they
chiseled ICs directly out of raw basalt back then, but even still! :)

The early VAXes took quite a few clock cycles to execute each instruction,
and the 11/780 could execute about 500,000 instructions/sec. Perhaps this
is where you're getting your figure from?
