The Cricket - ProDOS Clock Driver

I acquired a Cricket sound/clock peripheral on eBay. Therefore it is now critical that we have a conforming ProDOS clock driver for it.

STATUS: Work In Progress

Background

"The Cricket" by Street Electronics Corporation, released in 1984, is a hardware peripheral for the Apple //c computer. It plugs into the serial port and offers a multi-voice sound synthesizer, a speech synthesizer, and a real-time clock.

The included disks include:

  • /CRICKET/PRODOS.MOD which can be BRUN to patch ProDOS in memory with a clock driver.
  • A modified version of ProDOS
  • A utility to patch ProDOS on disk

Goal

Like the NS.CLOCK.SYSTEM (by "CAP") ideally we would have:

  • A ProDOS .SYSTEM file
  • Detects the presence of a Cricket
  • Installs a driver in memory following the ProDOS clock driver protocol
  • Chains to the next .SYSTEM file (e.g. BASIC.SYSTEM)
