Looks like I don't need to bother posting my version.

Hope it's of use to some of you anyway.

Sorry if I misled anyone with my post earlier today. I meant to say that I have a version compiled to run at $A009 with a manual start through SYS 40969. I did NOT mean to imply an autostarting image. For this binary I have simply replaced the first 8 bytes with $60 (RTS) to prevent the VIC from att...

Hi, When I worked on the original $7000 rom, I completely disassembled it and replaced the fixed references with references which are relative to the .ORG value. This allows me to re-compile it with just about any start address. Compiling a $A000 version should be trivial. I'll take a look tonight i...

Hi Mike, The answer to your first question appears to be that the commands are wedged in through the use of CHRGET. Although I haven't thoroughly dissected to code there are over 20 calls to $0073 so I think that pretty much confirms the method used. With regard to the second point, I'd already trie...

ps. I forgot to mention that there appears to be code within the Prog Aid cart that checks for the "A0CBM" starting at $B003. If it finds this then execution is set to jump to $B002. I wondered whether this was for the launching of a completely different cart - e.g. something like Vicmon w...

Hi Michael, Gosh that was a fast reply. The answer to your question is yes, I can relocate it to most areas of memory. I already have roms that run at $A000 and $B000. It will run in conjunction with the Super Expander with a couple of gocha's at the moment. The first is that it doesn't appear too t...

Hi everyone, I recently bought an old vih 20, which was my very 1st computer way back in the 80's, and started to show it to my kids. '3k!' they laughed. 'Expandable to 27k' I replied and you can extend basic. Then I remembered that with the Programer's Aid cartridge in block 3 you were limited to 1...
