The main advantage that I see with the 030 motherboard is the ability to support virtual memory when the new System 7.0 comes out; the SE cannot do this. As for other third-party upgrade paths, I don't know if the same holds true. > I also have a question about RAM. The SE has 4 spaces for Ram chips. It is > currently filled with 4 256K ram chips.

You can put the 2 new 1MB SIMMs in the first two slots, removing the first two 256K chips. This gives you a 2.5MB machine. Then you just have to figure out what to do with the other two. I have seen various people offer to purchase them for about $25 a piece. As for an SE/30, it has 8 slots. Memory has to be installed in sets of 4 SIMMs, so you must purchase 4MB, which would expand you to 5MB, or you could buy 4 256K chips and expand to 2MB. The second option limits you if you ever want to add more memory, because you would have to remove the 4 256K chips that you added and replace them with 1MB chips. -Michael -- Michael Niehaus UUCP: !{iuvax,pur-ee}!bsu-cs!mithomas Apple Student Rep ARPA: mithomas@bsu-cs.bsu.edu Ball State University AppleLink: ST0374 (from UUCP: st0374@applelink.apple.com)
