Anybody has the MJPEG chip for Dimension board?

Our research lab bought several Cubes in 1990 with the promise of that MJPEG chip for real-time video compression, but I never see one when the lab officially quit using NeXT in 1995.

Randy at Turbo Software has the only jpeg daughter card that I have heard of.

Are those for real?  (as in genuine-NeXT) His page is the only bit of information I can find on these cards...

They never made it to production.. but here is a short communication from when they were hopeful.

Within it says that with the hardware  compression the ND should do video compression on standard SCSI at 600k/s at an "OK" reslolution and that good resolution would require "fast SCSI" or large memory cache.
This was in 1991. Those familiar with "back in the day" video editing will remember that you really needed a striped RAID array ala avid or video toaster to handle the bandwidth needed.

If I recall, the prototypes were also very buggy still when they were axed. You really don't want one.

Here is a pic with the C-Cube chip integrated on the ND.
