CRASM v1.5 for Windows Command Line

Download CRASM15.ZIP for Windows.

CRASM is a portable cross assembler for 8-bit CPU(s): 6800/6801/6803/6502/65C02/Z80, written by Leon Bottou. You can find the original source code and distribution here: CRASM on Sourceforge.Net.

The Windows executable available here was compiled using MinGW.

CRASM's output is in Motorola S-Record format or in Intel's HEX format. If you'd like to convert the S-Record format to straight object/binary format, check out Ant Goffart's SREC2BIN utility.

Using CRASM and SREC2BIN can give you a convenient way to compile assembly for older computers such as the Tandy Radio Shack TRS-80 Micro Color Computer MC-10 (uses the Motorola 6803), TRS-80 Models I, II, III, IV (uses the Z80), and the Apple II (and other 6502 based computers, Atari 400/800, etc.).
