‘A Masterpiece in I/O Engineering’
The IMSAI Multiple Input/Output (MIO) board was a multi-interface IO board for the IMSAI 8080 and other S100-based computers. Available for 195USD in kit form and 350USD pre-assembled, the board gave the user access to one serial, two parallel, and two cassette interfaces which, in theory, would allow the user to connect a keyboard, printer, two cassette tapes and a teletype/CRT to their computer whilst only consuming a single S100 slot.
A product manual and board schematics for the IMSAI MIO board can be found at s100computers.com
