 Symon is a general purpose simulator for systems based on the NMOS
 Mostek 6502 microprocessor and compatibles.  Symon is implemented in
-Java.
-
+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.
