Hi Paul,

I think I have a HP 9845 board somewhere, but did you checked the connection 
between the processor and the pcb.
It's made by a combination of polymer with gold wire on it. This is the first 
time I heard of a bad processor, there is a much higher change of bad 
connections than of a defective processor.
The connector principle is the same as in the HP-41C from where it's known to 
cause some trouble.
Let me know the outcome if you're sure it's the processor I'll dive in to my 
parts stack ;)

Hi Rik,

As near as I can tell the connections are good, but I am pretty sure it 
is the CPU, the key had fallen out of the monitor cable and I 
accidentally plugged it in backwards, and when I turned it I almost 
immediately noticed the smell of magic smoke escaping.  The +12V 
regulator was wrecked, both the 723 and its pass transistor plus a 
couple burned foil traces on the power supply board.  I have repaired 
the power supply and all the voltages are good now,  the clock input to 
the CPU is good, however the clock outputs are dead, and I do not see 
any evidence of life from the CPU.  From checking after disconnecting 
everything it appears that the +12V output went up to more than twice 
its rated level.   I also fear for the ROMs in the machine but I can fix 
that as I had already designed a ROM card for option ROMs that I could 
easily modify for the system ROMs. I am still evaluating the full extent 
of the damage.

Hi All,

I was contacted via the greenkeys list for my spare parts of the two

Rod,

I don't use the lathe but I use a small dc motor in my vice , most of the
time the motor from the drive.
I use a "Eze-Lap Fine Diamond Pocket Stone 1" x6" (600)" to make them to the
right size.
Some times when I have to remove more material I start with Scotch Wet and
Dry 150 sanding paper wrapped around the Eze-Lap.
It's all about craftsmanship and a steady hand if you keep the motor running
at a steady speed about 50% of its nominal voltage everybody should be able
to do this.
After gluing the rubber to the capstan it takes me about 20-40 minutes to
get the rubber to the right size.
So you lesser mortals should be able to do this too.
For the tubing use something with the right inner size (a little smaller
than the hub) the outer size should be a little larger.
And look for an industrial hose/rubber supplier both PU and Neoprene should
work.

It shouldn't be too soft, soft rollers have too much friction.
But normal hose grade PU should perform ok.

It's important the tape cassette presses both switches but doesn't reach the
bulkhead (right name?).
The tape cassette is spring loaded and needs a little room to move (<1mm).
Put an tape without cover (just the ground plate) in the drive and you can
measure the distance between the drive wheel and the capstan ad a little
(about 1mm or less) and got the thickness of the rubber.
There is enough tolerance in the electronics, so you have room to
experiment.

I use a HP 10529A logic comparator on regular basis for fault finding in ttl 
circuits.
It compares a reference chip with the CUT (Chip under test;) it's a very nice

It's a bit like piggy backing just a little more sophisticated :0

Pete,

The VGA is IIRC SOG (Sync On Green) not all monitors support this.
If you have a HP-IB/GP-IB interface for a PC you can use Ansgars HPDrive to 
boot.
It's found at www.hp9845.net .
Also the drives used in the 9000/38X series are single ended scsi of external 
Fast HP-IB.
If you download the HP Basic 51. or 6.2 from the HP Computer Museum website you 
can boot of a the internal floppy drive and at least you know if the basics 
work.

What kind of tapes do you have?
DC100A (HP 98200A) are in most cases not compatible with the 9000/200-300 
series because they contain HP 9825A?B programs or 9835/45 programs.
The DC300 like quick tapes like the HP 88140SC / 150 Ft.  or HP 88140LC / 600 
Ft. 16 track tapes uses the HP 9144A or compatible drives.
For HP-UX systems HP used DAT tapes in the 90'th but I'm not sure if they also 
used them for instrument verification and test programs.
The programs I have are all on disc.
Before you put your old quick tapes in a drive you need to check if the drive 
belt is in good condition, if the tension is to low it will ruin the tape.
Drive belts can be retentioned by putting them in hot water >70C the belt will 
shrink then and go back to the right tension.
If you use the search function on the site you can find a mail from Christian 
Corti describing the procedure.

Pete,

Those are DC100A tapes used in the HP 98X5 series computers.
The programs are not compatible with the 9000/300 series.
I couldn't see the tape number on the label but I think it's a 9825A/B tape 
written in HPL.
Instrument software on this kind of tapes I've seen was written for the 9825.
You'll need a HP 9825 to read this tapes and copy them to a disk (8"  HP 9895A).
The tapes are very fragile, 90% the belts are stuck to the tape. 
And you need to warm the tape to about 50-60C to get the belt from the tape 
without peeling of the magnetic layer.
After that the belt needs to be reconditioned (see my earlier mail) and the 
tape may be needed to be baked (several hours in an oven at 55-60C).
After that you have only a few (1-6) passes to read the tape, before it becomes 
badly readable.
Replacing and removing the drive belt will need some practicing (I've done it).
When the programs are copied to disk it's possible to read them on a HP 
9000/200 series computer with HPL for the 200 series.
http://hpmuseum.net/display_item.php?sw=169
Which will not run on the 9000/382 or other processors higher/later than the 
68010.

Yes and no, you'll need a 9825B with the 98228A 9895/9885 Flexible Disc ROM an 
98034A/B HP-IB Interface and of cause a HP 9895A Disc drive ;)
And there will be a problem if there is a binary file on the tape, at the 
moment it is impossible to copy them, the 9825 is missing the tools to copy 
them. 
As far as I know an emulator isn't available (yet ?).
For which instrument do you have the tapes, I've some disc's for the HP 8566B 
and 68B SA's for RMB systems (HP 9000/200-300 Rocky Mountain Basic).
For some other equipment I should also have some files.

Aagh, I forgot about the HP85 some instrument programs where written for those.
So you have to check the part numbers of the tape and look in the service 
manuals to see where the tapes are for.
The 9875A and 9877A are external tape drives for the DC100A tapes almost 
unobtainable like the HP 9831A which is also very rare (I know just 3 including 
mine) .
The only 9875A and 9877A I know are at both the HP Museums.

The manual says you can't use a terminal on the internal serial port.
You can boot Basic 5.1 or 6.2 from disc, on the hp museum site you can download 
the images.
This is the default boot disk they made should work for every 200/300 series.

I'm not sure if you can run Pascal from a floppy disk.

So only HP-UX can run on a headless machine (no keyboard and monitor)?

I guess I'll have to find a VGA-to-3-BNC cable. And I'm not sure
whether any of my LCD monitors or projector can handle sync-on-green,
but I guess I'll find out. My old Nokia 445Xi 20-inch CRT could, but I
no longer have it.

Worst case, I can build a sync separator board.

Thanks! I found Basic 5.1 and Pascal 3.1 there and downloaded them.
It would be nice to get newer versions, but as long as those work on
the /380 it will be sufficient. Next I need to get an older PC running
to use Teledisk. All of my modern PCs don't have a built in floppy
drive, and I normally use a USB 3.5" floppy drive, but USB floppies
don't support non-PC formats.

I seem to recall that I downloaded some software to run my 29B (although I
have yet to work with it extensively), and that it did run in a DOS box under
Windows 98? Is that the '286' one you're referring to?

If so, maybe that won't run in a DOS box under the later versions of Windows?
Or maybe I have a different program from the one you're talking about? (Or
maybe I somehow downloaded an already-fixed version?)

Other than running under Windows 7, does it have any other improvements?
If so, I might be interested.

Whatever the case, if you would like someone to host it for open download,

The boards are also used in the HP 5420A/B Dynamic Signal Analysers and the HP 
5423A Structural Dynamics Analyser.
The boards belong to the 5443 control unit which is actually a M-series 
processor with some add-ons like the booster board and a custom front 
panel/keyboard.
The analysers consists of three 19"boxes containing the 5441 Display unit, 5443 
Control unit ant the 5441 AD-coverter and Digtal filter.
The boxes are connected through the MIOB  (Multiple Input Output Bus) a 16 bits 
bus used to communicate and control the various parts.
FYI the HP 5420 and 5423 were used to test parts of the space shuttle program.
Some other info of the units are on:

What I forgot, if anyone has tapes or info of these systems I would be very

Tapes are dc100 type of tape cartridges, typically starting with HP 05423-#

About power supply failures mine did have one, when under power after a few 
minutes there was a loud bang and the system resets.
Which would be repeated every few minutes, some investigating and measurement 
later I discovered one of the high voltage elco's shorted every few minutes.
Which started the power on cycle and resets the cpu.
After replacing those all voltages were stable and in range and the banging was 
over ;)

After some testing I concluded there were some faults in the cpu, being the 
lucky owner of an extender board I was able to fix all the errors.
The HP 2100 service manual and hardware course and engineering reference are a 
big help fixing the 2100 and as J says a set of known good cards can be of help 
too.
But knowledge of the working of the micro instructions is also a big help, IRC 
the micro instructions are described in both the engineering reference and the 
service manual both can be found on bitsavers.

The only weak point of the 2100 is the use of uCTL a Fiarchild DTL derivate 
used for IO drivers in the 2100 series.
Brent Hilpert has a lot of info on his site about those gates.

RE: 8 inch disks - help needed identifying format

Hi Denise,

It is a HP disc, probably for the hp 9845/35 series.
H tells you the drive type (9895A), 8 the controller select code, 0 the drive 
address, 1 the unit address (second disc in a unit, first disc will be 0).
Probably the disc will contain a large fata file of 1188 blocks, may be it’s a

Josh,

The HP 110 uses the same ac adapter (8V AC) as the hp 41, 71b and 75 series. 
Those are also used for some hp peripherals. I got lots of them but am on the 
wrong side of the big water. But it shouldn't be too difficult to get one. The 
batteries of the hp 110 are sealed lead acid types, they have a very long

charge.

If you have a HP 9895 and a HP-IB adapter for a PC, you can use the HPDIR

http://hp9845.net/9845/projects/hpdir/ 
Another way to read the files is using a HP 9845B/T or C and transfer the

RE: Flex Disc options for the HP 9825

[Rik Bos]

For what it's worth a small warning about the HP 9825 series computers.
The power supply doesn't have a crowbar(over voltage protection), so a
transistor failure in the Psu can be catastrophic.
On the other hand the two 9835's I have, which uses the same form factor and
almost the same power supply layout are HP modified with crowbars added.
It seems to be good practice to add some ov-protection to the HP 9825 supply
because the switching transistor and 723 voltage regulators don't have the
eternal life.
And there no certain prediction in how they fail, short or open circuit, I
found out the hard way several years ago.

-Rik

RE: Flex Disc options for the HP 9825

[Rik Bos]

Marc,

Building a crowbar is easy, just take a Zener a little higher than the psu
voltage eg 5.2V for 5V rail put a resistor of 1k in series take a Thyristor
big enough to take about 150% of the schort current and connect it to the
zener through a small resistor. I suppose you can do the math  ;) 
Be sure to put a crowbar on both the +12V and +5V and you could consider one
on the -12V rail but that voltage doesn't have a pass transistor but a 320K
voltage regulator which has a reasonable protection for over voltage.
The -5V is connected to the -12V through a zener.
Tony reverse engineered the schematics, you can download them a the HP
Museum website or become a member of the HPCC and order the CD with all
Tony's diagrams (a lot of eexcellent work).

It is a small extra pcb( with hp logo). Both my machines are build in Germany,

Fixing HP 3000 model 37 PSU

[Rik Bos]

Some time ago I acquired a HP 3000/37 micro, it has a faulty psu.

One of the mosfet controlling the power transistor BUX48 was shorted an blew
up the whole power stage.

Getting new fet's and power transistor wasn't the problem, but the regulator
IC also has blown.

The regulator IC is marked CC3896F made by SB and also has this number
'3713045', the only info I can find on the net is provided by the known IC
brokers from China.

I'd like to get this box running again, so I'm looking for the IC or a
replacement PSU which is an ITT PEC 3945 P/N 6064265.

Any other info about it like diagrams and datasheets about the CC3896F are
also welcome.

 

Thanks,

-Rik

I used hpdrive to backup the working one.

RE: HP 7945 disk format

[Rik Bos]

The ones I have (except of cause the working) seem to find trk0 and generates a 
drive not ready after that point.
I've done some measurement on the drives but they aren’t very consistent  with 
the service manual.
There seems to be a jumper configuration which places the drive in a test mode, 
I've seen it somewhere but can't find it online anymore.
I seem to have a hardcopy of it somewhere, I'll look it up, maybe it is of some 
help.

RE: HP1631D Logic Analyzer..Software???

[Rik Bos]

Glen,

Are you sure it's the HP 82161 drive that's for the 82176A mini cassette and 
not the DC100 tapes.
If it's the DC100 tape, it may be possible to read it with a HP-85 or an 9877A 
tape drive.
It depends on the tape format if the tapes are readable on other systems.

RE: What's the rarest or most unusual computer-related item

[Rik Bos]

My rarest item is a Diehl Alphatronics a very rare combination of 
computer/calculator it's a same kind machine as the HP 9820A or some Wang 
calculators from the era (early 70ties).
I also have the service manuals for this machine and some spares to keep it 
running.
Other rare items in my collection are the HP 9821A actually a HP 9820A with a 
cassette drive like the HP 9830.  
And a HP 9831A which is basically a HP 9825A with firmware to run HP 9830 basic 
and a different keyboard, but the firmware also works 1n the HP 9825A.
I also have part of a memory core module(6 layers) from an IBM 1401.

Chuck,

The tacho is a combined motor generator unit, it could be a good idea to read 
the adjustment procedures for the capstan tacho.
The behavior is electronic controlled and adjustable.
You can find the manual at the HP Museum site: 
http://www.hpmuseum.net/document.php?hwfile=2807
7970CEAdjusment...etc shouldn't be difficult to find.
The speed and transient behavior of the capstan should be checked and possibly 
adjusted.
You should also check if the capstan turns easy without noise.

It will work but you have to ad (noclean) flux before reheating the pins.
The solder will flow much easier that way.
There are special rework tips for this kind of work, to make the solder
easier.
The best way to do this is using solder paste and an external heat source
like hot air, IR-lamp.

FW: [VintHPcom] FS: HP 9000/400 apollo systems

[Rik Bos via cctalk]

Hi,

 

I’m a bit thinning out my collection.

I’ve 3 HP 9000/400 systems which have to move, 2 desktop (400t and 425t) one 
‘tower’(I think a 400s)

All of them with keyboards, one with a domain keyboard the others HP-HIL

These are heavy beasts I’ll ship them worldwide but sending over the big pond 
is costly..

To answer the obvious: no, I don’t sell the keyboards separate.

All the machines were stored working, but they have been in storage for a least 
3 years. 

So, the sell is ‘as is’.

Of cause, they are located in the Netherlands 😉

Please respond off-list

Then swapped drives, a unused 9 GB 80 pin with a Chinese 80 to 50

Did have to issue a spin up command and then copied the data to this drive
again with dd.

Powered all off, added a motor start jumper to the adapter and put it on the

Surely you must have a PLCC capable device programmer hidden away somewhere in 
your not so secret basement lab. And if you don't have one, why haven't you 
built one up from an HP-85 and some GPIO adapters?

I also have a PAC 65. I'll have to open it up and take a look. Wish there 
weren't so many screws involved. Whatever that 32-pin PLCC part is I should be 
able to read its contents with my BP Microsystems
BP-1610 device programmer. I could program a new one if I had some of the same 
part on hand.

It's probably something like a 28F010 / 040 flash chip, or something like that.
Look at which address lines are connected and you can figure out the size of 
the thing.
Most hobby programmers like Willem etc. will program those, reading shouldn't 
be a problem at all the foot print of these parts are all the same.

Sudden death of the HP 239X terminals by whiskering

[Rik Bos via cctalk]

 

Inspecting a newly acquired HP 2392A I found out the chassis was prone to
whiskering all over the chassis.

Whiskers are small metal hairs growing from pure metal (zinc or tin) and can
when they connect to a power line create a shortage and electric arc
damaging the electronics.

Made some pictures and placed them in:

It's best to remove them by using scotch brite or fine sanding paper, after
that paint or coat the chassis with a clear paint or other nonconducting
paint.

RE: hp 9145 capstan replacement

[Rik Bos via cctalk]

I think I misread you answer, 4mm tube for me is 4mm inside diameter, I suppose 
you mean 4mm wall thickness.
And the inside diameter of the 9144/45 is 12mm (~.5") the outside is about 18mm 
(~.7") (~3mm wall thickness).
I use polyurethane to make the new capstans, turn them on the lathe.

How do you figure that?  I've got a DC600HC cart here and it's the same 
dimensions as a standard DC600A cartridge--it is Iotamat preformatted,
without the usual optical sense stuff.   It was used on a number of QIC
(yes, it's quarter-inch) drives, such as the Kennedy 9455 and the ADIC 32-track 
drives.

As far as the capstan being too large, I suspect you may underestimate
the "stretchiness" of silicone hose.   Somewhere, I posted a photo if an
Archive 2060S drive with a red hose replacement capstan.

The hose comes in larger sizes, regardless.   I still need to refurb the
capstan on my 3M DCD-01 drive, but it's been too long since I've run into any 
2-track DC300 tapes, so it's not a priority.

In any case, the suggestion is offered for whatever value one can gain from it.

Tony,

Maybe this software catalogue will help you:

Onderwerp: [cctalk] Philips P2000C disk format

The quick version : Does anyone know the exact physical and logical disk format 
used by CP/M on the Philips P2000C portable computer?

The long version with explanations :

I am having reasonable success transfering files to/from disk images for my 
Osborne 1A (using cpmtools) and IBM5155 (MS-DOS, of course using editdisk). And 
I've even got the Greaseweazle to transfer those images to/from real floppies. 
The Greaseweazle still annoys me in that I know it's capable of a lot more if 
only I could work out how to do it, but at least it does something useful

[The less said about floppy disks shedding oxide and/or suffering from 'sticky 
shed' the better. I'm spending far too much time dismantling and cleaning 
drives]

Any, I'd like to do the same for another of my machines, a Philips P2000C cp/m 
'portable'. My machine is the version with 2 internal 40 cylinder single head 
drives (about 160K each, MFM) but I can also plug in an external 80 cylinder 
double head drive to handle this machine's other native format (about 640K).

Unfortunately, this machine is not common, and neither cpmtools nor the 
greaseweazle software has the formats predefined. I could add them myself -- if 
I knew what they were. Things like #sectors/track, sector size, #system tracks, 
 skew, etc.

It's not obviously given in any of the manuals I have, so does anyone know it 
before I try to work it out.

Alternatively there are rumours that the P2000C could read/write at least one 
more common cp/m disk type. The hardware should be capable of it, sure. Doe 
anyone know if software to do something like this exists anywhere for the 
P2000C. I can't find it on any of the obvious sites
