make it slower? how'd you figure that? I was thinking of doing that tbh

heard that from someone on tinkerdifferent who did the same thing, kinda assumed it would since the IIsi's onboard RAM is also used by the video chip on the system so the CPU and GPU are constantly accessing the same RAM area if something is running on the onboard RAM... and more stuff is being loaded in too. i did replace the RAM chips with 70ns ones from the 80ns originals, so maybe it is faster.

yeah, really no point in doing this unless you wanna take the time and effort to do it... lol. honestly it feels more responsive but thats probably just the 25mhz overclock and a nubus riser card (which also gives you an FPU) i got from a friend. now to find a good sca 80 pin scsi to 50 pin adapter with proper termination. @max1zzz still got any around?
