This program is for Turbo Pascal 3 for CP/M. It is an example implementation of an I2C bus master running in the SC140 main board. The I2C bus master is an SC144 board, and the slave device is an SC407 digital I/O board. Check https://smallcomputercentral.wordpress.com/ for more info on the boards.
