Microsoft MACRO-80 (often shortened to M80) is a relocatable macro assembler for Intel 8080 and Zilog Z80 microcomputer systems.[1] The complete MACRO-80 package includes the MACRO-80 Assembler, the LINK-80 Linking Loader, and the CREF-80 Cross Reference Facility. The LIB-80 Library Manager is included in CP/M versions only.[2] The list price at the time was $200.[3]
