The ram chip said -20 not -15, do you think it could work?

15 is faster than 20 so it's fine

The reason why it is 200ns BTW was that Apple was one of the early adopters of 256k DRAM back when the chips was expensive. By the time the 256k DRAM chips became more common, it was already mostly replaced by 150ns.
