RE: HEPAX-0C Prototype version ROM images.
Hi all,
As requested by the owner, here you are the CAT 2 listing of the HEPAX 0C prototype: -HEPAX 0C HAPPCHR HAPPREC HARCLRC HASROOM HCLFL HCRFLAS HCRFLD HDELCHR HDELREC HEPDIR HEPROOM HFLSIZE HGETR HGETREC HGETRX HGETX HINSCHR HINSREC HPURFL HRCLPT HRCLPTA HRENAME HSAVER HSAVERX HSAVEX HSEC HSEKPT HSEKPTA HUNSEC CLRAM CODE COPYROM DECODE 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. "Do not suppose, check it twice." |
