### Hepax Help

I've just started playing around with the Modified HEPAX_4H+ Module.
I don't have any previous experience with a real HEPAX Module so I am probably not doing something correctly.

1) The module shows up in my Active Modules List.
2) I can use HSAVEP to save a program in HEPAX Memory.
3) It shows up in CAT 2, and when I Call HEPDIR.
4) I can execute the program from HEPAX Memory, (after CLP it from main memory).

But when I execute HEPROOM I get nothing in response before or after moving a program there.

How much HEPAX Memory should I get after plugging in this module?
Is there some Jiggery-Pokery that I have to perform on the DM41X to initialize some of the DM41X memory to be HEPAX Ram like on the 41CL?
I can't find a manual specific to the "Modified HEPAX_4H+ Module". I am using the VM Electronics Manual as a guide but it assumes the actual HEPAX hardware.
I have probably missed a step when setting things up.
Any advice would be appreciated. Thanks.

### Re: Hepax Help

My setup is:
• AMC OS/X Module - 4P7 -BS4
• Modified HEPAX_4H+ Module
• Library#4 RevR51
• SandMath-V-#9 Bank-Switched 4x4++
HEPROOM: 1306 IIRC (now 1298, since I HSAVEPed a program).

BTW:
I just found that by pressing XEQ, then ON, the prompt changes from XEQ __ to XEQ ___ accepting 3 digit numbers.
Angel, does this come from one of the modules I loaded?
It doesn't do the same with GTO __ or LBL __

### Re: Hepax Help

It looks like HEPAX has to be loaded last?

I moved it to the end of the Active Modules list and now it works.
I have 1304 from HEPROOM.

No, my list is how they show up in Active Modules.

Good! If it works for you, then it's OK.

I believe the ordering in Active Modules is merely a hint to the system, as are metadata in the MOD file.

I think the definitive view of how things were actually loaded is stored in the rominit.log file on the FAT drive.

e.g. from mine (slightly edited for clarity)

R[0] 0 0 1 0 NUT0-N

It is strange. My original Active module order was very similar to Massimo's.
When I moved HEPAX to the end everything started working.
Maybe I got hit with a cosmic ray?

Yes. It is the Prompt Lengthener from Angel's OSX Module. It is supposed to work with GTO, LBL and a few others according to the manual.
Mine only works on XEQ as well... All others just turn the calculator off.

My 41CL is doing the same thing.

Oh, thank you, I missed it. It looked strange since it is assigned to the ON key...

Interesting, the prompt lengthener works flawlessly on my system for all native prompting functions, I wonder why not so for you guys. I'm using the MOD files form the shared ZIP container so that should not be a difference.

one thing to try is using the "_P6" version of the OS/X module, it's possible that the CALC_OFF event is intercepted by other modules "upstream" before getting to the OS/X.

Cosmic rays apart (possible but very unlikely this could possible be related to a bad allocation of the HEPAX RAM pages - that somehow got resolved after you modified the configuration.

One thing that does not work consistently for me is the permanence of the data in the HEPAX RAM pages during a HEPAX unplug/plug cycle. The contents is preserved if I use the same location, but it's gone if a new one is used. But HEPROOM always responds' regardless.

If your HEPROOM glitch returns, try HEPDIR on it and see if it works.
