<IIRC you're supposed to jumper some variable number of the diodes, dependin

The displays ate 90% of the power.

At VCC=VDD=5V the part would run all hte way to 3.2mhz. They claimed
at 10V it would 5-6mhz but don't believe it. I have one of the 10V parts
and the cmos is so slow that some of the signals come out a full clock
behind (and 155ns clock)! Keep in mind CMOS then was silicon gate and
something like 6-10micron rules, can you say SLOWWWWW. The SOS (silicon
on sapphire) part was a bit better. FYI: people that used the SOS part
werent going for fast as it's main appeal was low power (~10mw) and it
was RAD hard.
