  Sure - it's cheap, slow and ... junk-ware for a UNIX-system!

  Look at _ANY_ SCSI QIC-150 1/4" streamer and you find the answer
  yourself. Many system vendors have built-in 150 MB 1/4" SCSI streamers
  as 'maintenance tape' (SILICON Graphics, IBM etc.) for the distributed
  OS and products and you may even get an SCO-Unix installation kit on 
  that kind of media.

 Thanks for that statement, Rick!                   
 The real answer at all is a decent and stable SCSI environment!
 It seems that the MWC crew never heard the word 'industrial standard'
 (the Adaptec-1542 is such a thing!) and further it seems that they
 have no idea what it could mean to cling to industrial standards ...

 What MWC showed with COH' V4.x is real junk. You don't believe this?

  a) On my ol' 386sx/16 (YES, that slow!) with an ADAPTEC-1542B and 
     WangTek 1/4"-SCSI-Tape running SCO-ODT 1.1, a whole 150MB tape 
     restored in 45 minutes. (~60KB/s)

  b) On my COH'-Box 386/40-AMD (3 times as fast!, same SCSI controller) 
     moving a 60MB NEWS-area to a new disk took nearly took 2 hours -
     Disk-to-Disk!  (~8KB/s)

                    

>Tape drives that connect to floppy controllers suck.

 To say it more clearly: 
 Promoting DOS junk-ware is not the way to get a UNIX-like-OS fixed 
 on the market ... it is waste of time!

 With the ADAPTEC-1542B one will have ONE controller for EVERYTHING:

 	- Disks 		(NOT only two and sizes up to 2GB each)
 	- Tapes 		(60 MB to 5 GB, 1/4", DAT and EXABYTE)
 	- CD-ROM
 	- Printers/Plotters	(which support SCSI)

 ... and with high-performance, though! (3-5 times faster)
 Just wait and see ... 'til COH' comes as a swaping system ...


 Come on MWC guys - first promote what is worth to do. Maybe there is
 no need anymore, to bang your heads against junk-ware-drivers, if
 people realize what a decicated high-performance parallel peripheral
 bus-system offers. That's what SCSI _IS_! and what the ADAPTEC-1542B
 offers - not just a thingabum disk controller.
