According to this digital review article, the videotape subsystem is
marketed by Honeywell Inc. Test Instruments Division. It's called the
VLDS, transfers data in excess of 4MB/sec at .21 cents/Mbyte.

One version has SCSI. Current plans are to develop Unibus and BI capability.
The VLDS uses T-120 tapes with a bit-error rate of 1 in 10^12, costing
about $8 each. And end-to-end tape search can be completed in 90 seconds.

The VLDS currently lists at $44,000, and deliveries of the SCSI version
are scheduled for July. For more info:
