HEPAX - from the treasure chest

[SteenPetersen]

I looked at some of my other backup images:

SP2JUL
-SP RAM 0A
ROMTEST
RAMTEST
RAMTOG
HEXEDIT
DELETE
INSERT
COPYROM
CLRAM
HPROMPT
CTRAST
ROTYX
41EPROM
S

I do not remember how we managed to burn the EPROMs for the breadboard, but I guess the 41EPROM has something to do with this. Looking at the code it accesses HP-IL, so I could be something like this. We did have access to an HP-150 with an HP-IL interface which may have been used as part of this.
Looking at the S function, then this executes the ROM BLK command - basically moves the HEPAX module to a specific location.

There are a couple of functions added to the next backup:
SP1AUG
...
DECODYX
DECODE
CODE

Same CAT 2 on the next backup:
SP2AUG

Next I looked at DISASS:
-DISASSEM A
DISASS
^DIS

This could be my initial work on the Disassembler - it appears to accept input from X instead of Prompting for addresses. ^DIS looks interesting - it jumps to BANK4 - so it must expect something else to be located in that bank. So it appears to be some early work.

More to follow.
