Posted by: olePigeon on 2016-05-09 19:17:48 I have some extra RAM chips you can have for free.  Just pay shipping.

Posted by: Macintoshguy1984 on 2016-05-09 20:04:59 no thank you but thank you for the offer

Posted by: yuhong on 2016-06-25 21:18:50 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.
