I was going over some old cables, and found a strange
card in them.
It is marked C.A.V.I. interface and has a sticker that reads Cavri
Systems.
There is a 1980 date etched on the board, and under
the sticker it
looks
like it says BCD Associates. There are seven chips on
board, 2
DM7416N's a DM74LS14N, 2 Magnecraft W107DIP-5's, a Magnecraft
W118DIP-5,
and a rockwell 6520-11. There are 6 outputs: Monitor
V, Monitor A,
Audio
Ch1 and 2, Player V and Computer V, and a nasty HRS
rectangular
locking plug.
I suspect it might be for an Apple II, but everything
else was Wang
or
System36, so it could be anything. Does anyone
recognise this?
Sounds like some kind of interface to connect a computer, a monitor,
and a LaserVision player (or some similar device). Such systems were
used for training systems using video clips and stills. I remember
Jaguar using such a system in the mid-eighties; they shipped one to
each Jaguar dealer in the UK, with training disks for the vehicle
technicians -- but those were PC-based, with Pioneer LaserVision
players and fancy Sony monitors. CAV probably means Constant Angular
Velocity; which is what is used on LaserVision disks designed for
random access, especially picking out individual frames. The
Magnecraft devices are DIL reed relays, possibly for video switching.
If it doesn't have much else on it, I'd guess it doen't do any
genlocking.
Sorry, no idea what computer it fits.
