It implements I2C master-mode by bit-banging a couple of lines on the PC parallel port. Includes C source portable for both Borland and Microsoft compilers as well as a PostScript schematic of the needed interface circuit.

A simple 2-wire bus that allows micro-controllers and computers to connect to specialized IC's like videotext-decoders and DTMF generators.
