I happen to have a set of 4 spare 1 Mbyte SIMMS. Can I put these in my NeXTstation to get 12 meg of memory? In a Monochrome (and I believe the color nextstation, but not having opened one I can not tell) you can put only eight (8) main memory simms on the cpu board. These simms can be either 1 Mbyte or 4 Mbyte variety. You can mix and match 1 and 4Mbytes in groups of four (with the exception of some special 4mbyte simms that you can put in pairs), however you can not mix parity and non-parity without the next machine getting upset at you. So to answer your question: NO, not unless you remove some 1Mbyte simms and replace them with 4Mbyte ones... which obviously is not the question you are asking:-) NextAnswers covers this topic quite clearly. I recommend that people get together in their geographical regions to have NextAnswers accessible to them. A lot of answers can be found on-line through Next Answers or the complete documentation set... However the problem is that the whole documentation set is not available in the reduced 2.0 distribution and not everyone has internet access... pasc
