User's Guide: RasterOps "VideoTime" video capture card for Apple Macintosh Nubus computers.
The VideoTime card can capture analog video (either composite or S-Video) and create a live video window on the Mac's display. The card uses a special cable to connect between the Mac's display output and the actual display. The card takes the graphics output from the Mac and merges it with captured video to create a screen that contains both the Mac output and the live video stream.

This full size Nubus graphics card fits Macintosh computers such as the Mac II, IIx, IIfx, IIcx, IIci, Quadra 700, and some others with a full size Nubus slot. (It won't fit the IIsi and similar Macs that can't accommodate a long card.)
Emulating this? It should run fine under: Basilisk II
