Macintosh IIci Developer Note

This is Apple Computer's own developer documentation for Macintosh IIci, published in 1993. It covers the IIci's built-in video and its use of main memory as a frame buffer, the cache-card connector and its signal definitions, the three NuBus slots, and the RAM configuration rules.
Apple's developer notes are a different document from the Service Source repair manuals: the Service Source tells a technician which module to swap, while the developer note gives the electrical and architectural detail — rail currents, connector pinouts, power budgets and chip functions — that a repairer needs in order to make a go/no-go measurement. Several figures on this wiki are cited to this document.
