Eric Bal has a wealth of information on his web site
(http://www.ebbsoft.com/) concerning HP series 80 computers. There are also
links to suppliers who might be able to supply new belts.
Good luck!

Someone from my former home town has a bunch of MicroVAXen stuff
that's going to, he says, go to the scrapyard if no one expresses
interest. Any of the Bay Area crew care to negotiate with this guy?
Please reply directl to him. Thanks!

Time to let go of some more treasured junk.
I have enough miscellaneous parts to put together about 3 working
microVAXEN, with many spare parts left over. The hoard includes but is
not
limited to:
(3) BA23 cabinets, (2) w/ floor-standing tower setups
(~5) CPUS
(1) monochrome monitor for QVSS graphics system
(1) color monitor for QDSS graphics system (history buffs! this is the
system that X was developed on, (i think!))
(2) 1.2Gb SMD disks
(lots) 80Mb RD53 MFM disks
(3) TK50 tape drives
lots of the typical controllers, memory, et cetera.
various versions of Ultrix and VMS
etc.
----------------------------------------------------------
Here's the deal: highest bid takes all the stuff. I'm not really
expecting
anyone to pay much for this stuff (but you can if you want:-)). If
someone
would trade me a 486 or better clone box (or even motherboard) that would
be fine.
Or, if you could come up with a fixed-scan PCI card, i'd keep just the
color monitor.
Or i'd trade the whole mess for a 17 or 19 inch multisync monitor, but i'm
not gonna hold my breath on that deal.
If after a week or two no one has expressed any interest at all, it will
go
to a scrap yard.
***NOTE: I like to collect old stuff myself, i've got tons of it and i
sympathize with the obsession, but PLEASE, PLEASE do not send me mail from
Nova Scotia or Britain saying could i ship the stuff to you it's a pity to
see it trashed. I'll only deliver it local to the Berkeley California
area, and then probably only if you can sweeten up the deal for me as
outlined above.
Thanks much,

I have successfully restored old plastic to near its original condition by
wiping it down with a "hot" solvent (I use acetone). Be advise that what
you are actually doing is removing the very top layer of the plastic, thus
exposing the original color. How much damage you do depends on the quality
of the plastic, how "hot" the solvent, and how carefully you go about the
work. A little trial and error on the underside will give some insight as
to how well it will clean up. A little furniture polish or similiar at the
end will generally gring back the luster of the plastic that has been
deadened by the solvent wipe.
Please, no flames about this. I do not recommend, nor do I personally use
this procedure on any equipment that I deem too valuable to "clean up". I
also have discolored HP equipment which will stay that way. OTOH, I see no
reason not to clean up old Commodores, and the like, this way. As far as an
ADAM goes, the owner will have to decide. I have a couple and put them in
the same catagory as Commodores, i.e., clean-up candidates.

I have a somewhat old-fashioned colleague who still uses an HP-85B.
This morning he came and asked me why the paper advance on the built in
printer wasn't working, what was he doing wrong?
He had borrowed an old HP-85 from another section (who had thrown it
out, apparently - it had a red sticker saying "Equipment not to be
used"), but this also wouldn't advance the paper, so he had concluded he
must be getting something wrong.
I tried a couple of times to no avail, so I took the lid off. (Why do
they have to make the tape eject button so huge?). Not much poking
around to discover that the toothed belt that drives the paper advance
had perished and snapped. The rubber was mostly in dust all over the
place; the strengthening threads were wrapped around the drive gear on
the motor. The smaller toothed belt that drove the print head was also
very ropy.
So, we opened up the other 85. The same fault, with the remaining belt
in worse condition.
To conclude, then, does anyone know where to get replacement belts, or
what the HP part numbers are, or any other useful information?
Philip.

Ran mine for two years, sold it to a friend, who ran it another two years
before selling it to someone else... Who knows? Maybe one of you guys have
it now. To make sure, check to see if the black nameplate on the top of the
printer is glued back on... :)

First of all, I found a bunch more Apple things in my uncle's basement. Anyone
want? Manuals, software, etc. Visicalc, Terrapin LOGO, and some other ones are
complete packages. There are some commercial things from '84, '85. F.E. there
is an Apple II magazine that is all reviews. This is a 1985 copy with a
Lamborghini on the front, mostly about making the Apple II look like a Mac.
Now, for the second part. I have a //c, and my uncle has a II with an 80col.
card. Does anyone know if my //c can use a Z80 processor? I would like to try
CP/M on it. If it can't, does anyone have a Z80 card for a II, so that I could
run it on my uncle's machine? Also, any RAM cards, hard drives, modems, etc.
for the II and //c would be nice.
Thank you.

Do you mean the //c or the //e? The //c cannot take cards at all, being
the small flat white one. The //e can take all that you mentioned. I do
not know if the //c can take a hard drive, but I imagine so, if it is
external (of course). However, I have a source in Adelaide of //c 1 meg
memory cards - difficult to install, as you need to remove the cpu and
several other bits, plug the card into the cpu socket and put it all back
togeather again, but it is also the only way I know of expanding a //c's
memory.
Adam.
Merch,
I used to run one of these back in my teenage years. It was a pretty neat
machine, except for a few downfalls: Little third party support, not a whole
heck of alot of software to choose from and power supply was built-in to the
printer.
On the plus side: You could run CP/M on it, and yes, playing all those
Colecovision games on it was a blast too. I think the normal retail price on
the system was $599, but it quickly dropped to $499 the first year, and by
the time it was headed out the stores you could snag one for $199. There's
still a couple of ADAM user's groups out there, just have to search the web
for them.
