Summary: I love my DOS-73.


[ I wrote this in response to a similar question on the unix-pc network ]

I have had the board running for almost a year without major complaint.
Several protection techniques on software don't interact well, thus I find
myself in the ironic position of being able to run only pirated versions of
Lotus 2 or DBase III (ie those with disable protection schemes).
  DOS-73 (as it is affectionately called) runs under its own window in UNIX
and is very happy to co-exit. I often have very numerically-CPU intensive
tasks running on the DOS board (GLIM statistical utilities in particular)
which does nothing to degrade my UNIX performance.  DOS tasks that compete
for disk attention do noticebly decrease performance, as do tasks that write
a lot to the screen device (I guess the window manager has to service
these).
  Disk partitions are very convenient.  One can define 256 logical DOS disk
units (two work just fine for me) of just about any size.  I have a 300K C
drive and a 10meg D drive on my 40meg Tandom system drive.  I can run UNIX
and friends comfortably in the remaining 30meg or so.  I find the ability to
use the UNIX file system as another logical DOS drive (the E drive in my
case) amazingly convenient.  I have become the major translation station
between DOS users and various VAXen in our department via the DOS-73/UUCP
link.  I don't think this combination can be beat.
  I've heard rumors that AT&T has discontinued this Alloy product, too bad if
that's true.  But then I've heard that AT&T has discontinued the 7300 for
what that is worth.
