Just kidding, you probablely meant 100ns. Anyways, for TWGS you need 70ns I believe, which should be about round $15-20, I would guess. It's pretty hard finding high speed SRAMs out side of CA. (I'm going to visit my brother one day in CA and go to Fry's, I live on the East Coast. I think the TWGS upgrade come on they're own circuit boards, too. It's tough to upgrade if you don't know the pin outs and stuff. Better just to hand over the $100 or switch to the Zip GSX. The SRAM on the Zip GSX is socketed on the card, unlike the TWGS which it surface mounted and to upgrade you have to use those awesome expansion connectors... (sarcasm intended)... there isn't room on the TWGS to add anything. The Zip GSX uses highly intregerated ASIC to reduce the # f components to just 6-8 chips which includes the SRAMs. The TWGS, has to go to the smaller surface mounted devices to cram everything on the card. So there you have it. INET: whitewolf@gnh-starport.cts.com UUCP: crash!gnh-starport!whitewolf ARPA: crash!gnh-starport!whitewolf@nosc.mil
