Vintage C64 machine-language monitor cartridge with assembly, debugging, memory, and relocation tools.

ConsoleMAD listed one original cartridge-only unit at GBP 24 on 2026-07-30; it was missing its label. RavenWolf's tested USD 12 cartridge was sold out and had been recovered from a workshop with harsh long-term storage conditions. Treat every offer as an individual used item. The HES software and manual remain copyrighted, so this record does not present an unlicensed ROM download as a DIY route.
