- To: Fred Haines About: mload and z33 (12 lines)
-
- I had some difficulty with MLOAD zapping the first 6 bytes of Z33, as well. I
- think I was working on something Z33-specific using MLOAD to load it and then
- trying to run it. It would abort, saying Z33 was not available, but that
- would cause a warm boot and it took me the longest time to figure out what was
- going on.
-
- I found that MLOAD was calculating it's buffer space based on the BDOS vector
- at 06h. The cure is fairly simple: at line 44 of MLOAD24.Z80 the instruction
- LD A,L should be patched to XOR A to subtract from zero instead of six. I used
- ZPatch to plug an 0AFh (XOR A) into address 01B6h.
