- 4Mb of 60ns DRAM is abundantly available for about $150 in small quantities.
- That's less than 10% more than 70ns parts. My supplier tells me that
- he often gets 60ns parts when he orders 70 because his supplier is out
- of 70's. Keep in mind that both parts are manufactured exactly the same.
- The only difference is that the ones that don't test out at ~50ns get the
- 70ns label.
-
- I have run 70ns parts in a 486/33 with 0 wait states. They work just
- fine, but for the tiny price differential, I'd specify 60s.
