Hi all,
I have an important matter to discuss (important for me, interesting for you?).
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.
