	Eric,

	To go faster with your TWGS, you need to:

	1- Update 8/32 K cache II memory form AE
	2- Order from WDC (Not sure that it's still possible)
	   I order mine 2 years ago) the 65C816SPL (SA 9306A)
	3- Get the following Gals, I order mine two years ago
	   from AE !.

		TWGS 1A
      	  	TWGS 2B
        	TWGS 3B
        	TWGS 4B
        	TWGS 5A
        	TWGS 6A
        	TWGS 7A
        	TWGS 8A

	4- An 40Mhz Oscillator 1/2 TTL.

	and your TWGS will run at 11Mhz ..... Mine is working
	at 11Mhz with this config.


That's it.
