- PKE simulation code almost complete. Still missing:

Browse Source 
* handling of super duper packed UNPACK arguments
  * skipping of in-progress instruction on break/stop
  * interrupt generation to 5900
  * PATH2/PATH3 status checking & masking
  * ability to write to FIFO one word (instead of quadword) at a time
