Assembly Language Programming
I am currently developing a "source" program for my eprom and going to attempt rewriting the actual assembly language.
I've noticed a LOT of "virgin" territory (like x'898A-AFFF) that is totally blank plus a little area after x'F10D which have some small amount of data but is also basically empty too.
Does the ecm NEED x'B000 as the starting address of the program or can I alter the starting address to say x'9000 and free up some of this area for additional programming?
Also, is there any additional documentation on ASHC11.EXE about some of the options and is there any freeware that will convert the S19 object file into an actual BIN file (besides TunerCat's program?)
Lastly, I have noticed that while the AUJP BIN is quite close to the ANHT BIN there are some very real differences and it is not an exact match; thus the 8D hac is not exactly correct. Be careful when reviewing the instruction set of the ANHT when trying to determine how it works. You should verify to the actual machine code to ensure that the machine code is the same or you might be surprised.

geez, about 4 years ago i coulda answered the question of the obj to bin. I know if you search with hotbot or something you may come up with one but it'd be on a hacking/cracking/phreaking, etc, etc type site that has to do with viruses and such (which is where i got mine). I'll take a look on some of my zip disks and see if i still have it, but i really doubt it. I think i lost that disk.
