1.0 About
---------

Symon is a general purpose simulator for systems based on the NMOS
Mostek 6502 microprocessor and compatibles.  Symon is implemented in
Java.  It's core goals are accuracy, ease of development, clear
documentation, and extensive test suites for validating correctness.

The initial goal is to simulate a system with an NMOS 6502 or CMOS
65C02 central processor; one or more 6522 VIAs; and one or more 6551
ACIAs.  More functionality may be considered as time goes on.

2.0 Usage
---------

  2.1 Requirements

  - Java 1.5 or higher
  - Maven 2.0.x or higher (for building from source)
  - JUnit 4 or higher (for testing)

  (More to come!)

3.0 To Do
---------

- Finish core functionality.
- Finish command monitor.
- Refactor address decoding (second refactor to DRY up more).
- Clean up JavaDoc.
- Implement CMOS 65C02 instructions and NMOS / CMOS mode flag.
