[net.micro.16k] Cheap Unix Workstations

One system I would encourage you to check out is the HP Integral PC.  The
last issue of Byte (February) carried an article about it.  The hard part
about looking at one is that currently HP is not selling it through your
typical computer stores -- got to go through a rep I believe.

The Integral PC features are:

*  68000 based UNIX system packed into a portable package.  Folds up to a
   case about the size of a small portable sewing machines.  Weighs about
   25 pounds.
*  Uses custom HP IC for 3-d graphics.
*  Built-in Thinkjet (ink-jet) printer.  Prints 150 character per second.
*  Tiltable 9-inch amber electroluminescent display.  Displays 24 lines of
   80 characters each.
*  Comes with 512 Kbytes RAM -- expandable to 1.5 Mbytes.
*  Built-in 3.5 inch double sided diskette drive with capacity of 710 Kbytes
   per disk.
*  256 Kbytes of ROM contains the UNIX operating system.
*  Supports RAM disk such that a portion of RAM can be partitioned  to act
   like a second disk drive.
*  External HPIB port, two front ports for keyboard, mouse, etc., and two
   expansion slots for more memory, modem, etc.
*  Price is $4995.

Like the Apple Macintosh, the Integral PC uses windowing as a key element
in the design.  It allows up to 6 file windows to be open and active
simultaneously.  However, unlike the Macintosh which moves windows by
rewriting every pixel in the window, the Integral PC treats the windows
like "sprites" -- only pointers to the windows need be changed to move
the windows.

Unfortunately, I have not used it yet.  I have sat down and played around
with it but didn't know what I was doing.  I understand that the documentation
is extremely good and thorough.  A tutorial disk is included which will
take a new user through the system capabilities step by step.  The tutorial
takes eight hours to go completely through it (extremely thorough!).

One complaint I have heard from some folks is that they wished it had more
mass storage built in.  Originally, HP planned to put a built-in 3.5 inch
Winchester.  However, they decided that for a system to be truly portable,
and thus rugged, they were asking for trouble by putting in a Winchester
which cannot survive the severe shocks and vibrations the the Integral PC
is designed to live with.  If you would like to have more mass storage than
the internal diskette provides, (and for most applications, it is enough),
it is recommended that you buy an external Winchester that interfaces to
the HPIB.

I would also recommend that you check out the Radio Shack Model 16B and the
Data General One -- both of which also are UNIX portable systems.  I also
believe that Altos as well as Compupro make UNIX portable machines which
you should check out.
