Each version requires no more than 4k of memory. You may use just about any target address for the assembler you like. Simply change the .OR value in A1ASM.ASM and re-assemble the lot using the SB-Assembler which can also be found on the above mentioned home page. Do NOT run the 65C02 version of the A1-Assembler on a 6502 machine. That would result in all sorts of errors to occur.
