Re: Could someone educate me on options for HEPAX RAM size?

Hello, I am really new to Hepax, and trying to "ride" the (big) learning curve. I have a "curiosity" question for the knowledgeable people here by a "neebie" : how did Hepax manage to run programs in it's own memory, where HP41 failed to do so in it's extended memory (...

Re: Could someone educate me on options for HEPAX RAM size?

This is probably the easiest way to convert a single HEPRAM page into a standalone ROM with your own favourite collection of Focal programs. I am finishing the disassembler for HEPRAM pages (takes time, the devil is in the details) which gives insight in what is inside a HEPRAM module. Since you're...

Re: Could someone educate me on options for HEPAX RAM size?

Interesting! Evidently the work needed to convert a HEPAX RAM page to a standalone ROM module is less than I thought. ;) Gene: Please do not try what I suggest without a backup of your machine. I think it worked fine, but if you have the only copy of a program in RAM don't try it without a backup. ...

Re: Could someone educate me on options for HEPAX RAM size?

Global labels are turned into XROM functions. The drawback is that if for some reason, you add or delete a function 'in the middle', all other functions shift up a place - XROM calls are by number, not by alpha label. So make sure to put the most 'finished' programs first ;-) I figured that would p...

Re: Could someone educate me on options for HEPAX RAM size?

Angel... so what that represents is ... Hepax RAM pages in pages 8, 9, A and B. Each of those would be 4K of Hepax RAM. however, they are only useful if the contents had already been loaded with Hepax functions. Once loaded, the hepax module is then unplugged and the hepax ram still works to access...

Re: Could someone educate me on options for HEPAX RAM size?

Okay, so a 16 K Advanced HEPAX with 4 pages would be the maximum RAM configuration? There's no way to stack all of that into 4 banks of the same page, is there? Where might one find a module that's been configured for 4 RAM pages? The one on hp41.org seems to be a 2-page 8 K version.

Could someone educate me on options for HEPAX RAM size?

I've got a Standard HEPAX 1D "plugged into" my 41X, and the module seems to have 4 ROM pages and 2 RAM pages (8 KB). The two RAM pages are occupying bank 1 of pages 8 and 9. What are my options for increasing the amount of HEPAX RAM in the system? Can I fill the other three banks of pages ...

Re: Error while loading a RAW file ("TRY AGAIN")

install the HEPAX module and save your program there; it will become part of CAT 2 and won't take up RAM space. Werner What is the HEPAX module? I've heard about it and seen some comments but I haven't been able to figure out what it is and does. Conceptually it's a lot like the Extended Functions/...

Re: Request for feature: alternate font

Before this gets to be too much of a landslide, I'll cast my vote - no, please do not change the font away from the original-looking HP-41 font. If a change is considered, please make it a selectable option buried somewhere. :lol: smp Completely agree, don't remove the 41 font! I'd only want option...

Re: Request for feature: alternate font

Yeah, I wouldn't mind having the 42S font available as an option. It would certainly be nice for the multi-line program editor, if nothing else.
