Re: New member with early HP computers

 

Yes, it appears you have a T model, you have them correctly identified.  Leave out the A25 board, see if you get any further.  It appears that the boards are physically in very good condition.

Unfortunately I have no any working parts for substitution.

Is there a circuit  for memory module with signal check points?
I checked up the signals on internal slot (I think it's a part of 9825A model with system ROM module) and saw some signal activity on it.

I have spare parts but I am a long way away from you.

The B model has the OS ROMs along with most of the option ROMs and system RAM on one board (A24).  The T model has a second board (A25) with just RAM and a state machine that allows some of the RAM to overlay ROM.  This second board if present can be disconnected for trouble shooting.

The long ROM slot towards the right side of the machine is the slot for the 9825A OS ROM on the same circuit board along the front there are 4 slots for option ROMs.  Since most of the option ROMs are built into a B/T, only the Mass Storage, and Matrix ROMs will work all others will be ignored.

Paul.

The only schematics that I know of are Tony Duell's hand drawn schematics found at  http://www.hpmuseum.net/document.php?hwfile=1809 but they do not have labeled test points you need to figure that out for yourself from the logic.

Hello!

First of all excuse me for my English, I'm from Russia and have no practice. Therefore my posts may contain some mistakes so I'm sorry.

 I like vintage computers especially from HP. I have two early models -- HP 9825B and HP 85.
 Unfortunately my 9825 isn't work correctly -- I repaired the power supply module but the computer didn't resurrect :(
 
 I checked up all voltages and they are OK. If I disconnect KDP interface cable and make power on -- LEDs are light on and the beeper is sound on.
 I checked up the clock frequency -- all OK, approx. 6MHz.

Does the PVAL signal from the power supply go high?  If it remains low the processor will be held reset.

What was the fault on the power supply?  Some failure modes can result in higher than normal voltages going to components in the system, for instance I had one that to +5V pass transistor failed short putting about +25V on the +5 line.

Do you have any instruments like an oscilloscope or a logic analyzer you can use to troubleshoot?  If all you have is a meter troubleshooting may be difficult.

I would second what Craig said, I would clean the edge connectors and reseat them a couple time to make sure they are ok.  I had one that would not start up until I cleaned the edge connector even though there was no visible contamination.

If the memory board is not functional or is not responding to the CPU, it won't get very far during power up tests. Try reseating the connections between the board stack to see if that helps. If you have another memory board, you could swap it in place of the current one.

Re: R/362 Controller CPU Schematic - Updated

Right, I now understand my confusion over PROM/E2PROM issue!

Thanks to Rik uploading the 68040 Upgrade how-to I looked again at the Intel 27C210 & 220 datasheets and in the small print they mention that if the part is in a PLCC package (my board) it is an OTP ROM but if it is a DIP package (everyone else's board it seems) it is E2PROM.

Why they thought that was a good way to differentiate them without also changing a part number I don't know but given Intel are way smarter than me it confirms I'm just a bear of little brain and easily confused.

So I guess my question is still does anyone know if the Xicor E2PROM on the board needs to be pre-programmed in some way prior to it being able to store the configuration selected during the setup. The only reason I thought it might was because of the little printed label stuck on it which kinda matches the format of the labels on all the PALS, GALS etc on the rest of the board.

If the answer is 'yes' it looks like my Advin programmer can do it but does anyone have an image....?

Many thanks,
Adrian

FS. HP Integral

 

Trying to cut down and reclaiming some space, I’ve a HP Integral which may move to a new owner.

It works fine but the PSU generates a high pitch noise after switching on and the noise will disappear after an hour or so.

Probably a recapping of the supply will fix this but that’s for the new owner.

If interested I can supply pictures of the machine.

It comes with the HP 82919A serial interface and an 82925A 256k Memory module.

As most of you know I’m located in the Netherlands, but I’ll ship worldwide.

If interested please reply off list.

Yeah, HP/UX 9 shipped with sendmail (don't recall which rev), and the

the upgrade, assuming sendmail didn't give you hives.
I checked my archives here; I don't have it. I would like to have it,
though, so if anyone happens to find it, please send it along.

Of course, there are other options if you have a compiler and the will. 
I think HP/UX 8 or 9 was the first place I ran qmail; I know we ran
postfix on things of a somewhat later vintage (late 9/early 10?).
I would be a bit surprised, though pleasantly, if it had been 9.x.

probably an example. No sendmail.mc <http://sendmail.mc> but I’ll aim to

The file you found, sendmail.hf, is the help file. That's what's
dumped out on a port 25 connection in response to the "help" command.
The sendmail.cf file is nowhere near that simple, and nowhere near that
short. ;)

It's possible that the release of sendmail on that system predates the
use of m4 for sendmail.cf file generation. If it's 5.x, I just don't
remember if it used m4 or not. Let's hope that it does, but if it
doesn't, we can still get there. It has been a long time, as I moved
the mail servers that I'm responsible for to Postfix many years ago, but
I should be able to help.

Re: R/362 Controller CPU Schematic - Updated

So after a bit of careful label removal:

The 44 pin device is an Intel N27C210-200V10 which, I think, is just a OTP ROM (64KX16, 200ns, CMOS, PQCC44)?

The 32 pin device is the EEPROM! Xicor X2816BJ-25, I guess the fact it had a label made me assume it was a pre-programmed PROM/ROM and not E2PROM? From what I can see it only has a 'whole chip' enable so does not have a protected address range or anything so I wonder if a 'fresh' one can just be tried?

Thanks for the photo. I think the boot rom is the 44 pin chip next to the battery. The smaller one should be the ID PROM. So, I am right in thinking that the boot rom has a re-writable block for the configuration settings?

Thanks Rik,
So I was assuming the config information was held in ROM and there would be a separate EEPROM used to retain the config selections made. Perhaps I am wrong and the whole is within a single EEPROM but (presumably) with a write-protected area for the fixed config data?

At Martin's request I uploaded pictures of the CPU board here: https://groups.io/g/VintHPcom/album?id=94545

Thanks for the help!
