TWGS Upgrade question

[gachot@bonnet.enet.dec.com ()]

Hello,

	I have a TWGS which was working at 7Mhz, I upgraded
	it by changing the TWGS2B GAL, the cristal and the
	65816 chip. Now the TWGS is working at 10Mhz without
	any problem.

	Now I wanted to upgrade all GAL's in order to have it
	working faster. I found here in France 3 GALS:

		TWGS3D, TWGS4B and TWGS8B.

	Yes It's a miracle ;-).

	The only problem is that in the Transwarp GS/Zip Upgrade
	mini-FAQ, they are talking about TWGS3E (for above 10mhz 
	operation). 

	So my question are the followings: 

	1/ what are the differences between 3D and 3E
	2/ Is the 3D revision enougth for above 10mhz operation.


Many thanks for any inputs,

		-Erik.
