Well today I went down to one of the warehouses to look around for some
items I needed (didn't find them) and found the following items:
1. A box marked CP/M 2.2 for Commodore 64 in it was a manual and a large
black cartridge ( it has a Z80 microprocessor in it). I'm missing the
CP/M disk which contains both the operating system and some utility
programs. If anyone has a copy email me off list. THANKS in advance.
2. A green and off white plastic computer called a IQ 8300 with green
rubber keys. It has a POWER 3000 32K Ram black module about the size of
a Sinclair 1015 module. I have no Doc's or box for it and it's missing
the power supply as well. With have to do a google on this one, if
anyone has one or knows anything it let me know.
3. A Panasonic Personal Computer 32K memory model JR-200U. It's light
brown and silver in color with dark gray soft rubber keys and some dark
blue rubber keys also. It has a built in power supply with the cord
coming out the back. It also has the RF unit with so I will test it out
tonight.
4. A Sun type 5 kb missing four key caps.
5. Two HP model 9130A floppy disk drives.
6. hp 86 with 82936A rom drawer, 82937A HP-1B interface module,82900A
CP/M system module, and a 82909A 128K memory module.
7. hp 97 calculator missing adapter and battery.
All in all I had a ball opening boxes that have been packed for almost 6
years now while I was up North.

Those are the disk drives for the original HP 86. The later 86B used HP-IB drives but
on the 86 the drives connected directly to the main chassis.

Nice setup! I THINK I know where I can lay my hands on a copy of the CPM SW for the
module. I had four or five of the modules and finally gave them away after I couldn't
find the SW. THEN I finally found it! I did have a manual for the CPM modules and I can
probably borrow it back.
7. hp 97 calculator missing adapter and battery.
The adapter puts out 8 volts AC. The battery has four sub-C NiCad cells so it has 4.8
volt output. It should be easy to find an AC adapter, the adapters that are used for the
rechargeable battery packs in the HP-41 and for nearly all of the HP-IL devices fits and
works fine on the 97. I frequently find these types of chargers in the surplus stores. I
found so many of them that I just quit them. FWIW the charger is not adaquete to run the
97 without the battery however you can it off a decent power supply connected to the
battery terminals.

Let me know if you don't track it down. I'm pretty sure I have a copy of
the HP-85 CP/M software in one of the boxes in the bookcase behind me. I
got an HP-85 at a yard sale a couple of years ago that included two dual
3.5" disk drives, a bunch of manuals and carts and five shoeboxes full of
disks. I remember seeing a CP/M cartridge and docs, so I'm pretty sure the
software would turn up.

And all the HP90-series ('Topcat') calculators.
It is just 4 Sub-C NiCds in series. I can look up the polarity of the
contact springs in the HP97 battery compartment if you need it.
Actually there's about 6 or 7 if count all the foreign versions.
Sometimes they'll run without the battery but often they'll just set there and
flicker. The printer and card reader will most definitely not work without a reasonably
good battery (or a decent power supply) installed.
IIRC there is NO regulation in either of these chargers.

There are 2 types of HP97 charger connector (!).
The latter, and more common, one has a ridge in the middle. It takes the same
charager as is used with many later calculators (HP10A, HP19C (I think
those 2, anyway), HP41 rechargeable pack, HP71, HP75), and many HPIL
peripherals (82161 tape drive, 82162 printer, 82163 video, 82164 RS232,
82165 GPIO, 82168 Modem (I think), 82169 HPIB, 9114 disk drive, 2225B
thinkjet). And also on the 82143 HP41 printer, HP110 'Portable' and
HP110+ 'Portable Plus' MS-DOS laptops, and doubtless a lot more that I've
forgotten. These adapters are not hard to find.
The earlier series have a slightly different plug. I am not sure if the
later charger will plug in (I do know an old charger will not fit the new
machines). There is no ridge in the middle -- just 2 pins. Electrically
the chargers are indentical.
The plug on the old style charger is strange. It has a web in the middle but the web is
cut at angle so the plug can only plug in one way. The newer charger has the entire web
cut out and will plug in either way. Bear in mind that both chargers output AC so
polarity is not a factor. I almost never find the old style chargers unless it's with
a calculator so I neglected to mention them but I FREQUENTLY find the newer style ones.
The reason it was changed? People plugged the mains lead (the sort of
lead used with cheap cassette recorders _and with some HP calculator
chargers) straight into the HP97. That machine didn't like 110V or 240V
across it. The results were, I am told, spectacular...
ZOUNDS! I'll bet! Especially on 230 VAC!

True.
Incidentally, there's a little circuit in the 97 (a couple of transistors
and a resistor) to load down the output of the charger if the battery
terminal voltage tries to rise about the 6.2V Vss line. This will happen
if the battery is open-circuit or misisng.
If you use a real HP charger, then it's safe to power it up with no
battery installed (the HP charger has deliberately poor regulation
characteristics). It'll normally work well enough to do calculations,
although it won't print or read/write magnetic cards without a good
battery installed IIRC.

John,
