More H8D disk images!

[geneb]

They're at http://annex.retroarchive.org/disks/Heathkit/30Dec21

There's a number of original CP/M an HDOS originals as well as UCSD
Fortran and Pascal, also from originals.

The UCSD disks may have some kind of copy protection on them, but I'm not
sure. I created A2R images of them just in case.

Enjoy!

I hadn't seen Softech disks on 100K media before. May be copies rather than original dist'n? Also this is the first I've seen the Fortran and Pascal disks. Great!

Softech did the commercial implementation of the P-System (IV) based on enhancements to the UCSD release (II.5). To my knowledge, Heath only sold the Softech version in H37 format. Previously Heath sold II.5 in H17 format, which was not of much practical use given the limits of H17.

Hey Glenn,

   Everything Heath sold was by Softech including the original II. See the catalog on my site - https://heathkit.garlanger.com/catalogs/1982/Heathkit_Catalog_857.pdf it's on page 45. And says updates and support are available from Softech Microsystems.

I wasn't aware that UCSD had Fortran.

The H8D files were made from original distribution disks and they're all
hard-sectored. I'm pretty sure I've got the manual set as well - at least
for Pascal.

The reason I suspect copy protection is because the original disks and the
disks that are labeled copies both have bad sectors in the exact same
location. it could be coincidence, but I don't know.

[Mark Garlanger]

I also have them imaged and on my website - https://heathkit.garlanger.com/software/OSes/UCSDPSystem/ It's been a few years, but I'm pretty sure there were no errors when I imaged my copy.

Gene,

Very Nice! Do you have a link with all the files listed zipped? So, it is easier to download.

Also "Michel Bernard" installed UCSD Pascal on an SD card for a Z80 CPU. I think we should be able to installed it on the Z67-IDE+ to avoid using all the time the floppies.

https://hackaday.io/project/159973-z80-mbc2-a-4-ics-homebrew-z80-computer/log/168111-ucsd-pascal-for-the-z80-mbc2

Or we can put it on the GIDE controller (CF card) as well, if the Z67-IDE+ is hard to implement. This will equivalent to the SD card implementation by Michel Bernard.

Thanks,
Norberto

I ran the H8DUtil from the Z80 V4 board and re-created the two bootable floppies without any issues. When I boot either floppy, it asked to enter the space bar to calculate the baud rate and afterwards nothing happens. I just have one floppy installed.

 

Anything wrong with my setup?

Do you have two H17 drives? I don’t think it will boot without seeing two drives.

Thanks for the info Mark. I didn’t know SofTech also packaged the earlier release…

I have run both versions on the H8. The problem is they never included hard disk support, even though Heath was apparently intending to head that way (PART allows you to set up UCSD P System partitions). 

I think Pascal, Fortran and Basic were all supported, though the latter two were unbundled products which I’ve had trouble finding.

Added a second drive and it booted.

Oh nice, thanks Mark!

Each disk has a single bad sector in a different location, but the weird
part is, the user-created copies have a matching bad sector. No idea why.

If you've got multiple sets of originals, I would like trying to imaging a
set on my Applesauce to see if it gets the same bad sector or similar.
There's a potential that it's an issue with how the Applesauce is reading
the disk - The H8DUtility can't pull directories off of those disks - it
just shows garbage. It identifies it as a CP/M filesystem.

I do not. The Applesauce doesn't know how to read the filesystem for the
Heath CP/M or HDOS disks, so it doesn't offer the option of extracting
files. If you could point me to that information, I can pass it on to the
Applesauce developer and he could get that added in to the client
software.

tnx.
