SRAM is more expensive that DRAM No, it's flash RAM. It's non-volatile -- doesn't need any power to maintain its contents. That's why you can use it like a hard drive. SRAM can be accessed while power is being supplied to it (refreshed) so it doesn't impose wait states. DRAM is inaccessible when being refreshed and you wind up with wait states. It's still expensive. Then again, I can remember trying to save up $200 for a 16k RAM expansion on my Atari 800. _______________________________________________________________________ |\ ______________________________________________________________________\ | | | | | John H.
