The following equipment is available for immediate sale:

   Qty      Item                     Description
   ---      ----                     -----------

    1      HP9816S         PC (68000-based), 768kb(?), BASIC,
                           graphics option  [ see below ]

    1      Numonics 2300   Digitizer, 17"x32", .001" resolution,
                           16-button cursor, HP9816S software

    2      HP150           PC (8 MHz 8088; runs MS-DOS), 256kb

    1      HP150           PC (8 MHz 8088; runs MS-DOS), 512kb

    3      HP9121D         Dual 3-1/2" diskette drive for HP150
                           and/or HP9816S

    1      HP9133XV        15mb winchester disk + 3-1/2" diskette
                           drive for HP150 (and HP9816S(?))

    3      HP2392A         Terminal (with second RS232 port)

    1      HP2392A         Terminal (with Centronics-compatible
                           parallel printer port)

    2      HP2225A         ThinkJet printer (HPIB interface)

    1      HP2686A         LaserJet printer (RS232 interface)


All items except for the first two are known to be in good working
condition.  The HP9816S and the Numonics digitizer haven't been used
in a long time; they are believed to work, but are being sold on an
as-is basis.  As a quick check, I've confirmed that the 9816 passes
its power-up self test, and reads in an operating system from disk.

It's not clear exactly how much memory the 9816 has.  The sticker on
the outside implies that it has 256kb.  However, the power-up memory
test announces that it finds 786272 bytes; a peculiar amount, since
786272 is 3*256*1024-160.  Why the 160?  Beats me ...

Since the 9816 has a 68000 inside it, I suppose it's possible that
someone with time to spare and some amount of wizardry might be able
to get one of the 68000-based versions of UNIX running on it, but I
have no idea how hard this would be, or whether it's even feasible.
HP asserts that UNIX can't run on the 9816, claiming that at least
a megabyte is required (our 9816 allegedly has the maximum that can
be put onto one).  However, I'm not sure that I'm ready to believe
that there's no 68000-based UNIX around that will run on less than
a megabyte.  HP does say that a hard disk can be put on the 9816.

For more information, or to submit an offer for any or all of the
above equipment, contact

The boot ROM in a Series 200 (and series 300) has a very extensible set
of drivers for reading from disk, writing to terminals, and reading from
keyboards, until a "real" operating system (with drivers) is loaded.  
The ROM "steals" some low RAM (160 bytes, as a matter of fact)
for storage of tables and vectors.  Any operating system should preserve
this space.  From the amount stolen I would guess that you have a 3.0 boot ROM.
This is documented in the Pascal Workstation System Designer's Guide.

This should probably be amended to indicate that HP's enhanced version,
called HP-UX, does not run on the 9816.

Correct, with a plethora of capacities.

The 9816 has no memory management unit, which is why UNIX was never
offered on the system.  Any UNIX system run on it would have to do
memory management in software.
