HP-41, NoV-64 non-HEPAX software.

[Diego Diaz]

Hi all,

I received the request of a non-HEPAX version of the NoV-64 software a while ago.

Finally I got the time to include the required mods both in the ClonixConfig utility and the NoV-64 code itself. A simple check box is used to remove the HEPAX from NoV-64 and a modified version (NoV-64-N.asm) code handles the 12 ROM pages now available in a Clonix-D like fashion.

This mods allow the user to keep access to the 12 ROM pages of the NoV-64, which is most convenient when dealing with the latest bankswitched products from our M-code guru: ÁM :-)

You can select either keep two separated ROM blocks (6 pages each) or join them as a single all-in-a-row12 page block, in the same way Clonix-D can do.

If you choose 2 separete blocks, you can use control word at h'4100 to swap between them as usual (see NoV-64 manual for details).

RAM selection has also been preserved in the control word at h'4100 the same way it worked for the NoV-64. Note that some ROM with RAM writing functions *must* be included in your configuration in order to write into RAM pages (e.g. ASSEMBLER 3, David-2C, etc.)

Some functionalities embedded into HEPAX functions as the RAM page write protection or the Crash Recovery Function*, have been unavoidably lost when removing the HEPAX code.

Still preliminary, please let me know of any issue you may find.

Hope you find this useful.

All the best from Caribbean.

Diego.

* Crash Recovery Function is not part of the HEPAX code itself but it is intrinsically linked with the HEPAX auto-page allocation instruction (H'030) and cannot work without it.
