TWGS at 10Mhz Problems

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

	Hello,

	I have a TWGS with old GAL version working at 6.x MHZ.
	I order form WDC the new W65C816S
		from Digi-Key a 50.00 MHZ Cryst Osc
		from AE the TWGS2B, but AE was not able to send me all
		other GAL, as there no more available !?.

	I upgraded my TGWS, and I turn my IIGS on, and it was working at
	10Mhz I think. But sometimes ~10mnts the system hang or boing!!!.
	So it's not possible for me to work at this speed.

	Could someone tell me if I need to do something other, did I have
	to bough a new Chip or !!..

	Any help would be appreciate.

	Thanks,
			-Erik.
