Wiskunde & Informatica, VU, Amsterdam Lines: 13 I am planning to built an additional 64k ram into my c64. I want to do this by putting another eight 4164's into it. Looking at adverbs I saw that the 4164 is available as 120 and 150 ns model. Because the c64 is a slow computer I think the cheaper 150ns type should be sufficient. Is this assumption correct? What is the exact relation between the speed of the processor and the rams? In other words: What is the slowest possible ram that could be built into the c64? I sure hope someone has a clear answer to this question. Reg Lobee rcwlobe@cs.vu.nl mcsun!botter!rcwlobe
