Digital I/O Board with 32 Inputs and 32 Outputs
Use this board to connect your TRS-80 Model I to the outside world: 32 digital inputs and 32 digital outputs that can be accessed with simple BASIC language commands or from your assembler code. Inputs can be connected to switches, buttons or other digital sensors. Outputs can be directly connected to your TTL or CMOS circuits, or (using a transistor) to relays, motors, lamps etc.
The board operates from 5 Volts DC (supplied by the user), and is connected to the TRS-80 using the included ribbon cable.
The 32 inputs and 32 outputs are available at the eight 12-pin headers on the board.
