R/382 Computer can't find OS

Stan
 

I just pulled my R/382 out of storage. It was working when I put it away several years ago, but now when I power it up, it passes all the self-tests and then searches for an OS to boot but can't find one. The hard drive has HP BASIC on it, the drive is spinning, but that's as far as I've gotten.

The 2325 coin cell battery on the motherboard was (of course) dead, so I replaced it, but this didn't fix the boot problem. Might this be a configuration that was lost when the old coin cell died?

Any ideas?

Thanks!

Ok thanks Paul and Rik,

It is nice to see that burning the EPROM won't be a problem.

If there is enough interest I’ll order a new batch, the price depends on the total amount.

The boards will be produced at Eurocircuits and not in China, so the boards will be of a very good quality.

Jack,

You could probably use the same EPROM board as the one you have for the HPL II+ by just swapping the EPROMs.  I easily cloned that board using a S-100 prototype board that I trimmed to fit into the DIO card cage.

That would be very helpful - would it be BASIC 5.1?

Francois,

If necessary I can program EPROMs for you, I am located on the east coast in Halifax.

Hi Rik,

as my 9845 is still in a sad state I don't know whether I will need such a board.
Nevertheless I would be interested in having one at hand when it awakes.
I understand that the ROM board is a PCB which can be populated by the buyer with EPROMs and support TTL chips.
Can you give a rough indication of the order of magnitude of the costs?

The title on the document says literally software, however, the contemporary reference would more likely be firmware drivers.  Its a description of the 9885 disk drive hardware and the 9825 floppy rom for the 9885 with all the boot straps that are kept on disk that has been elaborated in detail for the benefit of the production release of the product. It should help interpreting the assembly code.

Re: Can I use a 98255A EPROM card to create a bootable language card?

Hi Stan

 

I also have a Dominique Berget BASIC ROM DIO card clones, version 5.1

You use up RAM when you load in the basic  but when you use a basic on a ROM  you save the RAM

 

There is a later version of HP basic  6.1  but most people seam to have standardized on 5.1

Hello Stan,

 

I know that Dominique Berget designed BASIC ROM DIO card clones, version 5.1 ( the latest BASIC version ).

You can find his contact email address at the hpmuseum.net site; if I remember correctly, one of Dominique’s older BASIC card projects is mentioned there ( 4.0 ?).

I don’t know if he has any of these boards left, or if there is a chance for a new production run; certainly that depends on the order quantity ( maybe you could initiate a common order, if others are interested as well).

I own such a board, and it works perfectly fine.

But the effort to produce them is high, allow for about € 200.- per piece.

The original BASIC 5.1 rom board ( at the moment I haven’t got the HP part number for it at hand, sorry) is extremely rare. A year ago or so one was sold on Ebay for more than $300, IIRC. So waiting for another auction for this one isn’t a reasonable alternative.

Perhaps you find a solution to build your own board. Otherwise, if you should decide to contact Dominique, please pass on my best wishes.

 

Best regards,

Michael

 

P.S.: There is one drawback of the ROM version of BASIC 5.1:

Unlike the RAM version, the BASIC code obviously can’t be modified.

That prevents the use of the BASIC compiler along with the ROM version, because the compiler tries to modify the BASIC code.

Betreff: [VintHPcom] Can I use a 98255A EPROM card to create a bootable language card?

 

I have a working 9826A and would like to have a BASIC language ROM card for it. Can I use a 98255A card with programmed EEPROMs to do this? I have access to a BASIC 5.0 ROM card with socketed EPROMS, so I can copy those if my idea is feasible. And if this will work, are there later versions of ROM BASIC (or ROM Pascal or ROM HPL) available?

Thanks,
Stan

Lee,

I'll be happy to share it with you (and anyone else) once I figure out how to duplicate it, hopefully in a digital archive.

Can you share the details on rebuilding your tape drive? I've found your other restoration reports quite helpful.

Thanks,
Jack

My 9830 is up and running and I have rebuilt the tape drive and it now works too. I would love to have a copy of the systems test cassette. Any chance you can make one?
