OK, enough conjecture! I dug out the file and REALLY read the description
of the video on hard drive system. Here are the highlights:

Images stored		1230 interlace, 2460 single field

Image 			Full screen, monochrome, single field or interlace

Storage media		20 Meg hard drive

Access time		65 Ms

Disk Organization	1 track per video field

Recording Method	Bit Cell Modulation       

Resolution		512 X 256 field mode, 512 X 512 interlace mode

Recording time		16.7 Ms

Grey scale		analog equivalent to 256 grey shades

Refresh			Continuous

"No frame grabber required, video signals are directly recorded"
"sequential or random access and display of images [for animation]"
"accepts NTSC, PAL, CCIR, SECAM"
"stores equivalent of 300 megabytes of video information"

The company data is:

Image Research Corporation
8260 East Raintree 
Scottsdale, AZ 85260
(602)998-1113

If you call, tell them a friend saw it at the Mesa trade show last year :-)
( I'm not affiliated with this company but my brother runs the trade show)


Now; can someone tell me what bit cell modulation is?


Thanks,
John Schuch
