This is Apple Computer's own developer documentation for Macintosh Centris 610 and Macintosh Centris 650, published in 1993. It covers the power supply ratings for each model, the expansion slots and their power budgets, the built-in Ethernet, and the video and sound subsystems.
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.
