 ## 5.0 Revision History
 
+  - **1.0.0-SNAPSHOT:** 10 August, 2014 - Added "Simple" machine
+    implementation, pure RAM with no IO. Added Klaus Dormann's
+    6502 Functional Tests for further machine verification (these
+    tests must be run in the "Simple" machine).
+
   - **0.9.9.1:** 27 July, 2014 - Pressing 'Control' while clicking
     'Reset' now performs a memory clear.
