Hi folks,
A friend of mine in the UK is looking for any info on the following boards. The CPU board
is marked ?VA 03-907023-00? and features a Z80 with 16K RAM and an 18.432MHz crystal. The
backplane is also VA and has 11 132-pin slots that aren?t all identical implying usage for
different cards in those locations. Voltages are +5/-5/+12V.

Those 11 slots are 100 pins, surely - the same number as the CPU board has.

Hehehehe, I looked at the silkscreen on the lower right pin and read ?66? not ?99? XD.
I?ve been up since 6am which is clearly having an effect.

Varian made a bunch of specialized systems/Devices used in Lab environments.

Thanks to everyone who?s replied! It?s a pity we don?t have a ROM board or anything that
might identify these boards further. It?s one of those things that will turn up
unexpectedly and I?ll think ?I?ve seen that board/logo before? then spend ages trying to
work out where I?d seen it :)
