Who is the manufacturer of the 1/4 inch tape drive for the Iris? I have heard that they also make a 300 MB drive. Is that true? Steve E-Mail: scfisher@dtoa1.dt.navy.mil

The drive you are referring to is probably an Archive 320 MB unit. markb -- Mark Bradley "Faster, faster, until the thrill of I/O Subsystems speed overcomes the fear of death."

As long as we're on the subject...
Has anyone ever used (or heard of anyone who has ever used) a 1/4 tape drive
unit from Wangtek ("Where Good Ideas Get Delivered."), model 5150ES in
a Personal Iris??
They are claiming to be a low priced ($950) replacement for the drive used
by SGI. I have more specs on this unit than I do on the one SGI provides, and
it appears to be a viable alternative.
Breifly:
Max formatted capacity: 250 MB
Data cartridge type: DC 6250
Recording Tracks: 18 Track Serpentine
Recording Formats: QIC-150, QIC-120
Read Compatibility: QIC-120, QIC-24
R/W Speed: 90ips
Recording Code: GCR
Transfer Rate: 1.8 MB per second
Data Buffer Size: 64 KB
Search/Rewind Speed: 90ips
Non-recoverable read error rate: no more than 1 in 10^11 bits
MTBF > 15,000 POH, 15% tape motion
MTTR < 30 minutes
[ there's more, but its environmental and power requirements ]
Physical: 5.25" half-height 1.625"H x 5.750"W x 8.300"D x 2.4 lbs.
I'd appreciate any TECHNICAL comments on why this drive may not be appropriate.
