It is probably a very early RasterOps 24 bit video card for the Mac II. The date on the card is earlier than the release for Color QuickDraw 32, so functionality will be limited. In a Mac II, it will probably work without drivers, slowly and incompatible with many System 5 applications. You need the drivers for it to work fully, and they only patch a few graphics apps to provide a 24 bit colour pallete. Try an ancient version of Pixel Paint from 1987/88. The card will hate System 6 or later.
My first guess is that the main board is a Colorboard 24 (ie 24 bit video via pallete matching drivers). The daughterboard is probably the NTSC or PAL card for TV display.
If the cards have been upgraded (check ROM labels), it may work with QD32 or System 6 or later Macs. 1988 is too early, I think, for the RasterOps frame grabber daugherboards.
