I picked up a couple of Compupros that were used in a Titan missile test
station. Each one has a Compupro 286 CPU, 64^H^H 128 K S-RAM card, EPROM
card, system support card and Interfacer 4 card along with a number of
custom cards. The operating system for them is in EPROM. These were used to
operate a ultrasonic test machine by remote control. Each test stand had a
turntable and gantry that would rotate the missile and run the test head up
and down until it inspected the entire missile body. Each test head had
four large ultrasonic transducers for detecting flaws in the missile. These
computers generated the master timing for the ultra sonic pulses and
converted the return signals from analog to digital then fed the data back
to another computer for further processing. They could be operated at up to
200 MHz PRF. They also took care of things like controlling the
programmable attenuators in the RF receiver. Most of the connectors on them
were replaced with "Canon plugs" and an extra power supply added for use by
one of the special cards. An extra fan was also added inside. All of the
custom cards use gold SMA connectors to connect to each other and to carry
the RF signals. The custom cards have some really neat devices on them such
as flash A/D converters, very fast S-RAM for buffers, switchable
attenuators, a crystal with 10-7 accuaracy, etc.
I was going to convert these back to standard Compupro configuration but
if anyone is seriously interested in them I will consider interesting
trades or $$.
PS I have lots of manuals for them too including schematics and theory
of operation for the custom cards.
