Alternative 60 Hz input

For only a few dollars, a single chip all-in-one microcontroller could be programmed to generate a 60 Hz sine wave and feed it to the S-100 RTC pin. Alternatively, the output could be a square wave and be sent straight into the RTC card's counter, bypassing the Schmitt trigger input.
