@ -27,3 +27,23 @@ Successfully tested on real hardware. (Laser 128EX, including at 3x speed.)
## Build
Requires [cc65](https://github.com/cc65/cc65). The included `Makefile` is very specific to my machine - sorry about that.
[CRICKET.SYSTEM](cricket.system.s) is the result of the build.
## 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.
