Has anyone |succesfully done this? I called AE and asked them (before 900 #, thanks |god) and they said "Don't do it, it most likely won't work", but I think |that might just be salesman talk. Anybody tried this? The cache upgrade on the TWGS, stinks. You could get 4 32K high speed SRAMs for the GS for that price. Just expressing an opinion. That's Western Design Center (WDC)... you should read the article... the 65816 still requires a "shmoo" 65816, and the ~5.5v... which means you have to get a variable voltage regular and also some resistor & capacitors to adjust the voltage. You have to figure out the values of the RCs your self and TWGS doesn't give you a place to put these things anywhere like the Zip GSX.
