# Beeper, Clock, Switch Board

Timer/clock, beeper and switch input interface.

The clock is a 15 bit stopwatch and uses 2 of the 16 bytes available on the I/O board. It has a resistor/capacitor time base, can be switched for 0.1 or 1.0 second intervals.

An independent beeper is on the board and an extra output bit is available to output a logic signal.

Inputs are provided for a manual switch which can be sensed by the computer or any computer function.

Sample programs are included to introduce the user to these features, e g., a program to translate keyboard input into Morse code (can be output on the beeper).
