aka 9826. It's a 8 MHz 68000 CPU baed system
that runs HPL (HP's
version of APL), BASIC or Pascal. Most of the OS were disk based but you
could get them on plug in ROM cards. The really interesting thing about the
OS is that you canhave multiple OSs (and muiltiple versions of the same
one) on the same drive or even multiple drives and you can select the one
that you want it to boot. Very nice for tinkering. All in all, it's not a
bad machine. They're wided used as HP-IB instrument controllers.
We were very impressed by the 68000 processor, both the fact that it used one
and the processor itself, since it's a bona-fide Motorola model, and an
expensive gold and ceramics one at that. Very pretty to look at, just like the
ROMs.

I wonder if the handle is original? There was an
option for some kind
of handle from HP but I've never seen one.
As absurd as it seems, it may have been intended for certain portable
applications by design, what with the space for a battery pack in a
compartment in the bottom. OTOH, the handle and the small shock absorbing feet
both seem to come from a furniture shop, not a computer one. =)

That's not a problem, the keys from most of
9000 200 series machi8nes
will fit it.
Oh, well, isn't that nice, I'll just go to the shop and buy some HP 9000/200
keytops then. ;-)

Yes, software is available. I have it but it's
almost impossible to
duplicate. You have to "build" the system from files on the distribution
disks, then you save it as a new system file. The problem is that the
system file is too large to fit on a floppy disk so there's no way to
distribute it except by shipping a complete hard drive with the system
installed on it or by making copies of the original distribution disks. I
have copies of a number of different versions of all three OSs that I've
picked up on hard drives but I've never been able to find ANY original
distribution disks. That leaves shipping complete hard drives as the only
way to distribute OSs for the moment. And we're not taling about just
shipping a bare hard drive. The drives use the HP-IB interface so you need
the entire unit which is about 13 inches square and 5 inches tall and they
weigh about 15 pounds. Your best bet would be to check the surplus
sources in your area and see if you can find any HP hard drives (7957,
7958, 9133, 9134, 9153 etc etc). I've found that frequently they still the
OS on them.
I know of no surplus sources in my area. I'll have the check the university
cellar when the semester begins, though, they use some HP and HP-IB equipment.
I used to have a long detailed article about the HP
9000 at my website
but my ISP deleted them. You may be able to find them in the cache at
google or one of the other search engines. Search for "HP 9000 200 series
computers".
Riger will do.
