Add-on dossier
A linkable lifecycle record for hardware expansions, app ecosystems, firmware upgrades, cases, radio parts, and post-event badge experiments.
The stock firmware included a Z80 emulator running CP/M with classic software hooks such as Zork and Sargon, turning the badge into a tiny retrocomputer.
