Apple Disk Attachment Interconnect Configuration Guide

The Disk Attachment Interconnect Configuration Guide is an internal Apple memo with a matrix describing all the ways the various floppy drives made by Apple could be connected to their computers. It is dated September 8, 1982 and the “IIIr” mentioned probably refers to the revised Apple III released in late 1981. The “IIIe” probably means “III enhanced”, later released as the Apple III Plus.

It also describes how the unreleased UniFile and DuoFile floppy disk drive products would have been used by customers.
