The NEC-PCVCR is a VHS Video Casette Recorder (remember those things?) that was special - it had a rs-232 port on it and almost frame-accurate video transport. The
The software was written in the beginning of 1991. It was written to run on Windows 3.1., with a companion program that controlled one PC-VCR written for MS-DOS.
The software allowed you to independently control two PC-VCR's. You can use one to create a scene list from your video footage. You could use the VCR as a "poor man's laserdisc" (remember those things?). Or, you could create a scene list and the software would do an A/B roll and copy the scenes to the second PC-VCR in the order that you requested. Basically, a "poor man's video editor".
I just found a copy. e-mail me.
e-mail me, I have some old example code written in C for both DOS and Windows
