On the other hand, you can get an Archive Super Scorpion 125MB drive quite
cheaply -- well under $1,000.  They are in short supply, as they've been
discontinued by the maker, but we still have a few (I think).  Other vendors
are probably the same there.

The 1542 Adaptec controller >is< nice.  No gripes there.

Archive Viper 150MB tape drives in SCSI format are well under $1k as well.
They even have a >new< 525MB (yow!) drive.  We're getting one of those on
evaluation; they're not much more expensive than the 150MB models.  The one
drawback is that like most QIC drives, they can read but not write the lower
density media.

I would say either ISC or SCO.  Then again, I haven't played with ESIX.

NO!  The ATI bus mouse is not recognized here by either SCO or ISC's unix,
although it does work fine under MSDOS.  Neither ISC or SCO will support
that configuration, and ATI doesn't know why it doesn't work (nor do SCO or
ISC).  It may be 90% Microsoft bus mouse compatible, but it's not 100%.

Correct.

>As to laser printers, get an HP LJ IIP (low cost, low running cost).

Especially if you don't mind doing a little hacking.  I understand that the
IIP can take LZW compressed input -- which will make the printer run
god-awfully fast compared to the LJII.
