Hi folks, I am considering buying an SE/30 w/ a 40M hard disk. I have a question: If I expand the memory to 4Megs, can I still use color later on if I want to? For what I know, these both need expansion slots and I don't know how many there are or are necessary. (How about an external b&w monitor?) Also, any suggestions on what memory I should get? Any suggestions and comments are welcome, not only those related to the question. Please send email. Thanks, gb bohus@math.rutgers.edu

The Mac SE/30 has eight SIMM (Single In-line Memory Module) slots and one PDS slot (Processor Direct Slot). The SIMM slots are for RAM chips and the PDS is for a single add-on card such as a color video card for an external monitor, an ethernet card, etc. Here's a rundown of how you could configure your Mac SE/30 memory-wise: # of 256K SIMMs # of 1-meg SIMMs # of SIMM slots used Total RAM 4 4 1 meg 8 8 2 megs 4 4 4 megs 4 4 8 5 megs 8 8 8 megs As you can see, there are two types of SIMMs: 256K and 1-meg. They can be used together, but a technical rule says that you gotta fill those SIMM slots four at a time. All possible combinations are listed above. You should also be aware of the speed rating of the SIMMs you need. The SE/30 needs SIMMs that are rated at 120 nanoseconds or faster ... the smaller the number, the faster the SIMM, i.e. 80ns is faster. >Also, any suggestions on what memory I should get? We often buy from Technology Works. 80ns 1-meg SIMMs are currently selling for around $50 each. (800) 688-7466.

All Macs (well, Plus and beyond) have special slots just for memory expansion. The SE/30 is unique among the "compact" macs in that it has two banks of four slots, just like the II family. To add a card for use with a color monitor (or ethernet, or ...) you use the 030 Direct Slot, which is completely different and seperate from the memory slots. To add memory to the SE/30, you have to go with four SIMMs at a time, so expanding to 4MB involves removing the 1MB already in there (4 x 256K). A better idea is to _add_ 4MB for a totoal of 5MB.

Thanks to all who answered. As someone has put it, I had my slots mixed up. Now I am much better informed. Thanks again, gb
