# 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:
* [x] A ProDOS `.SYSTEM` file
* [X] Detects the presence of a Cricket
* [x] Installs a driver in memory following the ProDOS clock driver protocol
* [x] Chains to the next `.SYSTEM` file (e.g. `BASIC.SYSTEM`)
Just need to try it on real hardware now...
