ASM80.js

The Assembler for the 8bit CPUs

Installation

$ npm install asm80 -g

Usage

$ asm80 [options] filename

Assembles given the file, e.g. test.z80, into two files: test.hex (binary) and test.lst (listing).

Filename has to be the last parameter.

Options are:

• -o, --output <file> Output file name
• -t, --type <type> Output type [default: hex]. Available types are: hex, srec, com (for CP/M), sna, tap (for ZX Spectrum), prg (for C64), bin (use directives .binfrom and .binto to specify memory range to export)
• -n, --nolist Suppress listing (.lst file)
• -m, --machine <type> Processor type, one of the following: Z80, I8080, C6502, C65816, CDP1802, M6800, M6809
• -h, --help See HELP

Machine type can be omitted. Right CPU is determined by file name extension (-m option overrides this decision).

• Intel 8080: .A80
• Zilog Z80: .Z80
• Motorola 6800: .A68
• Motorola 6809: .A09
• MOS 6502: .A65
• WDC 65816: .816
• CDP 1802: .A18
