HEPAX-0C Prototype version ROM images.

I dropped a note to Steen who developed the code @VM - let’s see if he has something to add.

As requested by the owner, here you are the CAT 2 listing of the HEPAX 0C prototype:

DECODYX
DISASS
HEPAX
HEPAXA
HEXEDIT
HPROMPT
RAMTEST
RAMTOG
READROM
ROMTEST
WRTROM
XF
XFA

As you can see, there are a number of differences with the production units and some function names were changed afterwards (some of them "fortunately" changed: e.g "DISASS" -> "DISASM" :-D

Although it has less functions there are a couple of them, that were removed from production modules: RAMTEST & ROMTEST.

To no one's surprise, RAMTEST checks if the RAM page "n" addressed in "X" register is ok . It shows "n:NO RAM" if pointed to a no RAM page. On a good RAM page it shows "n:RAM TESTING" (for quite a while) and then "n:RAM OK". It shows "n: WRT PRTCTED" if the RAMTOG commad has protected that page.

ROMTEST shows the code of the ROM in page "n" addressed in "X" register (in reverse sequence if there are several banks in that page: e.g. 4, 3, 2, 1 for HEPAX) and then CHECKSUM OK or CHECKCUM ERROR depending on the case.

Best wishes.

Diego.
