guys, i have a 68000 board with an eprom emulator at 1Mbit/sec, i can test whatever you want, but please, i do not want to use an other assembler, i have a gnu toolchain for m68k and a sierra C 68k (a pretty C compiler for Dos, it's a professional suite).
have you also considered to use a project designed in C instead of assembly ?
what about LUA instead of basic ?
