# The Cricket - ProDOS Clock Driver

# 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.

"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.

## Notes
|
||||
|
||||
I ended up disassembling both [NS.CLOCK.SYSTEM](ns.clock.system.s) (to understand the SYSTEM chaining - what a pain!) and The Cricket's [PRODOS.MOD](prodos.mod.s) and melding them together, adding in the detection routine following the protocol in the manual.

|

Other files:
|
||||
* [GET.TIME](get.time.s) just prints the current ProDOS date/time, to verify the time is set and updating.
|
||||
* [TEST](test.s) attempts to identify an SSC in Slot 2 and the Cricket via the ID sequence, to test routines.
