Point your camera at any chip pulled from an Amiga, a C64 or an arcade board — Retro Chip Vault reads the markings and tells you what you're holding, what it does, and how it usually fails. THE CHIP ENCYCLOPEDIA • 198 retro chips documented with interactive pinouts and technical references: CPUs, video, sound, memory, logic, custom chips. • Interactive pinouts with numbered, tappable pins and electrical roles. • History notes: where each chip comes from, what made it matter. • Repair notes: the failure modes techs actually see on the bench. • 76 classic machines mapped chip by chip — Amiga, Commodore, Amstrad, Nintendo, arcade boards and more. • A symptom checker: pick "no display" or "won't boot", get the ranked suspect chips — matched against your own stock. AI CHIP SCAN Photograph a chip's markings: the text is read on your device, offline, with no account and no AI key needed. For worn or ambiguous packages, plug in the AI of your choice — Apple Intelligence on-device, or your own API key with the provider you prefer. Your keys stay in your Keychain; nothing is ever hardcoded or shared. YOUR WORKSHOP • Track up to 20 chips: quantities, condition, storage location, favorites and low-stock alerts. • Keep a repair log per machine, linked to the parts you swap. • Print or export any chip as an A4 PDF sheet: pinout diagram, pin table, history and repair notes (Pro). • Manufacturer datasheets for 120 of the 198 chips (TI, Motorola, Intel, Zilog, NEC, Yamaha…), cached on device for offline reading. RETRO CHIP VAULT PRO — ONE-TIME PURCHASE No subscription.
