Description: An authentic technical documentation set for the IMSAI 8080 Microcomputer system. This lot includes the official User Manual along with specialized engineering notes and schematics dated 1977 for Dynamic RAM operation. The materials provide deep technical insights into the S-100 bus architecture, memory refresh cycles, and system logic used by one of the most iconic machines of the early 1970s.

Manufacturer: IMSAI Manufacturing Corporation (San Leandro, California)

Condition Description: This is a vintage original document set from 1977. The pages show age-appropriate tanning and minor handling wear consistent with a 45+ year-old technical manual. The text, complex circuit schematics, and logic diagrams remain clear and legible.

True Condition: See pictures for true condition. Please note: I am uncertain if this is a complete manual set; it is being sold as a historical archive as shown in the photos.

Extra Notes: IMSAI documentation is highly prized for its professional engineering standards. This set is essential for anyone maintaining an original IMSAI 8080 or the modern "REPLICA 1" systems.
