Next month, I hope, I will get some of the very first ** 4 Meg-SIMMs **, but a friend of mine told me the other night that there are problems with some piece of system software that the new chips won't be recognized. This is what I know and here are my questions. Can anyone out there help? 1) 4 MB SIMMs won't be recognized at all in Plusses and SEs, right? Why not, it's really a pitty :-( 2) In the Mac II, the following things happen: - The motherboard looks at the first 4 SIMMs and checks if these are 16 MB parts. If it doesn't find them, the next lower MB (KB) SIMMs are searched for (16MB -> 4MB -> 1MB -> 256KB). - Then, the second 4 SIMMs are checked if there are the same SIMMs as in the first four rows or if there are lower parts installed. 3) Is there somewhere a problem for me that makes it difficult or impossible to access this memory with the Mac OS? (I think, with Unix that should be no problem). Thank you very much for your help. As soon as I'll get them I will send a short report on these SIMMs. Gary T.
