Leaving the hobby

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? M. K. Peirce Rhode Island Computer Museum, Inc.
