Hi Steen, all,

Some of us are sitting on the edge of the chair while waiting for these contents to be available. :-)

A couple of names in the listing provided by KimH called my attention (and many other's for sure).

Look forward to reading from you.

Best wishes!

Diego.

I should have a LIF image ready by Sunday morning European time... sorry it takes some time, but work is getting in the way more than I would like....

8 hours later.....

Well - it is raining, so here you go. Have fun

Floppy 1 - VM

CAT :MASSMEM

Took the floppy labeled "HP-41 VM MCODE" - file by file - to ILPER and stored it as a DAT file on HP9114B image

Hope it works.

If you have suggestions or asks, let me know.

There is a second floppy called ROMS - mostly ROMS we already know. I'll look into this tomorrow.

Hi,

Not in a hurry whatsoever... after 33 years some weeks up or down won't make any differece. :-D

Best wishes.

Hi Bob,

I'm not very good with emulators, so, if you manage to extract these BANK1 - 4 ROM images (which may be another HEPAX proto) it will be great to have them loaded into a NoV-64d ;-)

Best wishes and have a nice weekend.

Hi all,

I've had a good time playing with these files. :-)

Extracted the BANK1 - 4 .BIN images and converted them into .ROM files.

The result is HEPAX-1A version which I've included into an archive here.

Hopefully I'll have a .HEX file to be directly loaded into a NoV module along the day.

Curiously enough its CAT 2 listing is quite different from both, previous 0C prototype and 1B (which IICR was the first production version)

I'll leave for you the joy of discovering these differences.

Best wishes and have a nice week.

Diego.

Thank you Kim for uploading the files! - it appears there are indeed some interesting treasures in it.

Diego, can you share the CAT 2 from the 1A version - I may be able to shed some light on this - if I can remember...

I am a bit surprised that we cannot find all HEPAX versions, but let us see what is hidden in the two other sets of HEPAX bank images.

Thanks,

Hi KimH,

Thanks for sharing this .DAT archive. :-)

A note regarding the "appealing" TOUL0B & 0C images: These are NOT the TOULOUSE ROMs althoguh they may be some early implementations from which the latter were derived and shows same XROM#12.

They show up on CAT 2 as "TOULMATH-0B" and "-0C" respectively and contains a number of M-coded math functions.

Still to check other unfamiliar names like "ARBEJD" or "NYBOOT".

Regarding the HEPAX image included (BANK1-4) on the previous archive, is shows "HEPAX-1D" on CAT 2 but its content is not exactly the same as the production "1D" version we're used to see.

From the "TEST" images, TEST1 has the HEPAX XROM#7, but shows "-TEST ROM A" and only contains five functions:

-TEST ROM A
ROMTEST
RAMTOG
RAMTEST
SAVE
GET

Have a nice day. ;-)

This is very likely the Toulouse Math ROM. I've been searching for the bits of this ROM for a long time, without success. Even Emmanuel Compes, great expert in french ROMs, didn't have it.
It seems the project has never been completed.

The Toul. Math ROM project was mainly driven by Bernard Jousse and Eric Aubourg, and has been discussed in several PPC-Toulouse and Micro-Revue journals.
Some of the latest status can be found in Micro-Revue n°6 and following.
And we can read in Micro-Revue 6 p.62 (translation of mine):
"In MC, Eric [Aubourg ?] is in touch with Steen Petersen (PPC-DK 3, PPC 9583) who transforms his HP 41 into a HP 15, but a better one".
Small HP-41 world.

[Edited: the complex functions of the TOULMATH 0C are described in Micro-revue 15, p32.]

ARBEJD is WORK in Danish, maybe Work in Progress or a work related project - Steen to reveal
NYBOOT probably means NEWBOOT

SteenPetersen · (This post was last modified: 10-20-2020 08:40 PM by SteenPetersen.)

OK - you are really finding some nuggets ;-)

I am happy that you are able to recover the material I have kept for so many years - I will try to provide some insights as far as I remember.

When comparing HEPAX 1A with 1B, then the only differences I spot in the list are the last four functions - 1 through 4. I do not remember what these are used for, but are likely some kind of test functions - if you disassemble them you may be able to tell.

I think the TEST images are the very first code I made to test the four bank switching. We had a couple of challenges - the first challenge was how to test the bank switching in the EPROM part of our prototype breadboard. We could not do this from a RAM program - it had to be from EPROM code. So I wrote some code which I think were the TEST images. The question is then how do we burn the EPROM from this? I wrote another program which converted the images to EPROM addresses and the corresponding byte value per location - in the correct format required to be stored in the EPROM. I ran this program and printed out the EPROM addresses/bytes on the HP-41 printer (you may be able to find this program somewhere on one of the disks as well). We then visited one of our suppliers which had an EPROM programmer with a hex keyboard and one line display. I spent the best part of an hour and manually entered the EPROM content in the programmer and then we burned the EPROM. Finally we stuck it into the breadboard and it worked! - we were able to run ROMTEST to check it out. If it had not worked, then as you can see there were many steps where this could have gone wrong...

On TOULMATH I was helping Eric to create an image of the code he created - I did that a couple of times. It looks like you found those images. Thank you for the link to the french magazines including JPC - I found an article I wrote back in 1985 (http://www.jeffcalc.hp41.eu/divers/files/jpc-25.pdf - on page 30) about a proposal for Machine Language bar code - take a look. This article explains two functions in the BOOT ROM - namely MCP and MCSCAN - have fun ;-)

The ARBEJD (WORK) appears to be a work in progress image - I would be curious to see what you find in this. NYBOOT (NEWBOOT) looks like an updated version of the BOOT image - maybe the same just stored in a 640 register file.

Another fun fact - when working on all the functions we wanted to add to the HEPAX module, then we had more than the 64 functions than you could have in a single module - as also mentioned in the manual. So this is how both the XF/XFA multi-functions as well as the HEPAX/HEPAXA multi-functions came about.

Regards,
Steen

A very interesting reading about M-code barcodes.

I didn't even know it was possible. :-)
