Completed the Analog-to-Digital Converter and associated Inverter Circuit. The A/D Converter is so that Mike’s on-board microcomputer can detect the position of the directional detector potentiometer, as well as read the joystick. The Inverter Circuit is needed because all output lines on the KIM-1 go high (ie, to 1) when ‘reset’ is pressed-so the programs will output 0 for high, 1 for low and the TTL lines will be inverted.
