Hello,
There may be a Hewlett-Packard 9845B computer coming up
for sale in Queensland, Australia.
As much as I'd like this machine, it would be too expensive
(for me) to have it shipped from down under to the
United States.
If anyone closer, or better funded, is interested in this classic
machine, contact me off list and I'll give you the details.
Cheers,
Dan

Yes it is in Massachusetts, if you have any referrals please let us know.
It includes tape drives, disk drives, 1401 printer 2540 card reader punch
etc
Thanks

The 4331 is (in my opinion) eventualy the single most desirable
classic /370 Machine for a proivate collector. It's reasonable
compact, but got all the bells and whistles of a real IBM of the
early '80s. Ok, the odd I/O chanels are a minus, but beside that
it can't co better for the spacewise challenged amon us.
It looks almost as if he thinks he may still get money, but he
might learn soon that he should be happy if someone is willing
to pick it up without having him to pay for that service.

Joe,
The RQM Systems Power-Start boot loader board has 16 'load address' switches
(set to C000h), 8 'sense' switches, and 8 each called 'IN 376', 'IN 375',
and 'IN 374' (obviously octal representation). There is a 'Board Enable'
paddle switch on the right, tons of basic TTL and a 74S472 PROM (512x8 bits)
with room for one more.
Probably loads the disk controller start code...

Good point.
But, I need to know which chip goes in which
position...
Using your idea, it looks like the two missing chips
are the 6809 and the 6883 (which would make sense, as
Bob sold those as spare parts).
But, I don't think it would be a good idea to put the
wrong one in the wrong place, and I still need a set
of ROMS.

>Apple //gs - $20 each
Wanna buy some from me?!? At that price I'll be happy to sell you a few.
>Apple //c new in box - $50
If it is really new in box, then yeah, I could agree with that price. But
I have seen MANY things claimed as "new in box" that are really "we used
it for 12 years, and before throwing it out realized we still had the old
box so we repacked it". I have seen very few really new in box items, so
I am sceptical to those claims.
>Mac Plus - $5
>Monitors - $5 each
>Misc. drives - $10
>"scads of software and manuals" - I'm assuming "scads" is worth about $25
I consider all of the above to be "Thanks" prices. ie: they really aren't
worth anything, but you feel compelled to give the person something for
being nice enough to save you the effort of digging thru the trash to get
it.
In my opinion, Thanks prices don't really add up. Kind of like coupon
actual value prices. Its worth $1.00 during the transaction, but if you
add the value up, you find it is worth half a cent. So 10 monitors @ $5
each would not equal $50, but rather maybe $10 if you were feeling good.
>Including a "new in the box" //c and "scads" of software? That's what I
>would value most in the lot mentioned.
Got about 3 moving boxes full of assorted software just a few months ago.
All that was headed to the dumpster (I intercepted it on the way). About
half Mac, half PC. I also got 2 paper case boxes of IIgs software not
much before that, probably 20 or so titles, most in their boxes. All free.

I went under the assumption that it could refer to Mac monitors and hard
drives since there are Macs included in the list. Actually, now that I
think of it, if we are talking about Apple II hard drives (regardless of
size), then those are worth something as they are much tougher to find.

Yes, we differ here. You fit into the exclusion that I mentioned. That
is, you care about having real copies of software. So to YOU the software
might be worth something. There are lots of people like me that could
care less about original copies, vs getting an "abondonware" copy off an
FTP site or so. To people like me, software is of no real $$ value.
What's interesting here is I see your point with your pricing. You
consider some items to be of value, that I don't. And vice versa (I find
some value in a Woz IIgs). So it just goes to show, when pricing things,
you can't rely on one source for info, and you should shop around to
figure out the best place to market stuff. Maybe this is why eBay prices
are always so high... with the wide audience, they increase the odds of
hitting someone that lays value on the item.
And I'm still amazed that you would give a decent price. I had thought of
you as a person that will always claim things are worth far less than
they are just to keep prices down. I miss judged you... it must just
really be a pure hatred of eBay instead. :-)

The thrifts I go to here in Chicago are not too bad about desktop systems
($10-$20 for 386/486 boxes, $5-$20 for monitors), but any laptop _starts_ at
$50, even XT or AT-class ones. A marginally useable 486 will most likely be
$150. I usually don't even bother with the hardware -- I go looking for old
MS-DOS software.

I'm guessing that all of the items that you had to give away for
free have already been distributed. If not...I am interested in the
very last item. If so, do you know where I can get one? :)

Well, I finally got around to testing the PSU on my 11/34. I measured at the
backplane connectors with no backplanes plugged in. Everything checks out
except for the -5V and +20V. Accordingly, the LED at the bottom of the H745
brick (regulator 1) does not light. However, some of the other voltages
coming from the H745 (according to the BA11-K FMPS) seem to be OK.
Does anything in the machine even need -5V or +20V? If not, can I leave the
bad brick in place? I have: KD11-EA, KY11-LB, DL11-W, MS11-JP, M7850 parity,
DZ11-A, RK11-D. I'll be adding a RX11 at some point. Someone enlighten me,
please. :-)
I'm pretty sure I have a spare brick.
Also: what are these signals on the 6-pin backplane mate-n-locks?
- AC LO
- DC LO
Something I learned: If you have a H785 brick in your 11/34 BA11-KA cabinet,
ignore what the 11/34 and KY11-LB manuals say about battery backup and the
rotary power switch. You can indeed have a battery backup with a BA11-K, and
the switch on the KY11-LB works as you think it should. You must connect the
ribbon cable from the H785 to the corresponding connector on the KY11-LB, or
the H785 won't work. You must NOT connect the one-wire connector from the
H785 to P4(?) of the AC input box, or else your machine won't turn off,
regardless of the rotary switch. Clear as mud?

Hi all,
I'm trying to track down a 387 math coprocessor IC for an old 386-based
Linux box that's going to be doing a bit of numbercrunching for me. Has
anyone here got an AMD or Intel (AMD preferred) 387 coprocessor rated at
40MHz (-40 part number suffix) that would work correctly with an AMD
Am386DX-40? No, before you ask, the 386DX does *not* have a built in
mathco - the 486DX was (IIRC) the first DX-series chip with a built-in
coprocessor.
Thanks.

Hi all, I have put my Intel MDS system on hold while I await
some hardware information in the mail. I am resurrecting the
second half of my project which is to get a Northstar system
up and running so I can develop the ISIS-II code again. The problem
I have at the moment is that I need the schematics for the MDC-A4
controller. I have two manuals on the double density controller
but nothing on the one I am using. Does anyone have the manual
available with troubleshooting info or at least the schematics.
I am more than willing to scan docs I have in trade.
I am off troubleshooting the controller because it will not write
properly. I can load a fresh copy of DOS, customize the I/O and
actually run DOS now, but I can't update and make a new copy
because of the write issue.
I did manage to fix an Applied Microsystems EM180B Z80B emulator
today so I could enter the console code and run things.
Thanks!
best regards, Steve Thatcher
I am curious if anyone ever had one of the Legacy Enhanced Floppy Controllers for the PCjr, was ever able to duplicate one, or know if it was ever possible to modify the current controller to take on a 1.44mb capacity.
I have a Racore unit with a modified 3.5" 1.44mb drive that acts as 720kb, and is fantastic, but would love that extra storage space if available!
Brian
oops!
Guess that was wrong.
I can remember using a Tandy Controller on a Dragon 32
once. But, I guess that one had hacked Coco ROMS.
That might be what I do with this unit, hack a set
Coco ROMS to go into it, just to get it working again.
With a new unit at $35.00, it might not make much
sense to try to get this one working again.
My Coco III is also dead. Green box with no text. I
think the 6809 is bad. At least, that's what I've been
told about these units. So, I'd have to desolder it
and put another one in just to diagnose it.
I may do that some weekend when I feel adventurous.
Suddenly caught the old computer bug....

Is anybody here familar with this stuff? I picked up a HP disk drive with the ChemStation software installed and I'd like to know more about exactly what kind of computer it was SUPPOSED to be used with. I searched the net and one site mentioned that it used a HP 9000 300 but that's all I've been able to find out. I got the Sw working on a HP 9000 217 but I'm having some problems with the display. Oddly enough, the SW won't run on my HP 9000 320 or 380!

Did you see the auction? As you say, it never made it to the online catalogue...
Also, the plotter I'm on about has definitely been saved now. He's possibly going to give it to his son's school, possible eBay it, or possibly sell it to one of you lot for ?pittance, provided you take it away (from Norfolk).
Personally, I don't need/want it, and have no means of transporting it anyway, but the offer is there for the taking.
I've decided to try to get my Dragon 64 running again.
I got it from Bob Rosen of Spectrum Projects. He
stripped all the socketed chips from it, however.
So I need to find a set of Dragon 64 ROMS, and
identify what chips go in U19 and U15.
I'm pretty sure that the one closest to the ROMS is
the 6809E, but not sure of what the other chip should
be.
What makes this more difficult is that this is not a
British Dragon. This is an American one made by Tano
Corporation.
I wish I had just offered him some money for the
original chips way back when...
I can buy a whole new Dragon for $35.00 + S/H, and if
I can't get a set of ROMS and the missing chip cheaper
than that.. I may just do that and keep this one as a
spare...
I wish I still had the Dragon disk controller also...
I know I can use a Tandy Controller, but I think I'll
need a different Disk Basic ROM for it. If anyone can
help with that, I'd be obliged...
Regards,
Al Hartman
P.S.: On the Apple II pricing discussion in a
different thread. I agree with Sellam re the pricing.
The buyer could easily resell the items he didn't want
on eBay and get the prices that Sellam quoted.
And who knows if those IIGS's contain RAM boards or
even Super SCSI cards that would be work $15.00 for
the RAM card, and $40 and up for the SCSI cards.

I've got one too - but I didn't get a system tape or a blank tape with it. If anyone wants to part with a System tape and a few blanks, well, my email address is philpem {at} dsl {dot} pipex {dot} com.
