Developed means here, they disassembled the ZEUS objects and created C files out of the ASM listing like I do. Probably they didn't figured out the "ldl rr4,rr2" part of the original ZEUS object (which was probably there) too and they decided that how it is done now has the same effect. So - you can say all sources which contain german text are created based on ZEUS disassembled objects so they are not "original" ZEUS. all the source files containing a "whatstring" from the version control system are files created by me by disassembling the original ZEUS objects. One interesting thing for example can be found in the WEGA-debug.c: callr _gethex and r2,#16128 ldl rr4,rr2 and r4,#32512 ldl |_stkseg+~L1+8|(fp),rr4 is the ASM code from the original object What they've tryed at EAW when writing the debug.c file was: #define UMASK 0x3f00ffffL #define KMASK 0x7f00ffffL [...] kadr = (unsigned int *)((long)(gethex() & UMASK) & KMASK); But this gets compiled into: callr _gethex and r2,#16128 ldl |_stkseg+~L1+8|(fp),rr2 which is the same because - when the AND with 16128 happend, an AND with any higher value won't change the register - so the optimizer probably decided to remove the and with 32512 - which is not removed in the original object.... A friend of mine is working on a P8000 emulator - 8Bit is kinda done, 16bit part is "in progress" - no idea how long it will take him to complete it since I have no circuit plans of the 16Bit part - only the original (good documented) Firmware Sources. When it is done and it can be released officially you can all enjoy the feeling on working with a P8000! ;) -- Oliver Lehmann http://www.pofo.de/ http://wishlist.ans-netz.de/
