I am thinking of upgrading my 2MB IIsi to a 5MB configuration. I know I need to purchase 4 1MB SIMMS. Would 80ns or 100ns be better for the IIsi? Also, what are some of the better mail-order places for SIMMS in terms of price, quality, speed of delivery, etc? Thanks in advance for any help you can give me. :-) Amy Shelton ashelton@cshu.encore.com

Regarding upgrading your IIsi memory: I suggest you consider getting 4 2 meg simms to give you 9 megs total rather than 4 1 meg simms to give you 5 megs total. In order to upgrade memory you have to "toss" the chips already in the computer. So be sure you get enough. I have a IIsi at home with 5 megs and I am upgrading it to have 17 megs. I find 5 megs to be restrictive, and really think you might be happier with a 9 meg system. I have an 8 meg FX at work and find that amount of RAM to be adequate. I know system 7 with virtual memory will help, but still real RAM is better than virtual memory. It depends on what you are doing of course. I'm mainly doing color graphics and some program development and I find 5 meg just doesn't cut it. If you are just doing word processing and spreadsheet type work 5 megs will probably be O.K. Just for a case in point, I tried to compile a sample C++ program that came with Programming with MacApp in C++ and it could just barely compile on a 5 meg system. There was just a couple hundred K left. My system is fairly big due to inits, RAM caching, lots of fonts and so forth. Similarly, if I have a color drawing program running I can only open one window, and can be running no other programs. Dave Neff neff@hpvcfs1.HP.COM

I have a price list from the UCLA computer store, and they claim that the IIsi is only expandable to 5MB (17MB with system 7). My question about this is, why is the IIsi limited to 5MB? What's different about it - the other machines in the II series can handle 8MB with system 6.x... John Price * * * * price@uclapp.physics.ucla.edu Where there is no solution, there is no problem.

The IIsi is only configurable to 2, 5, 9, or 17 meg. This is because there is 1meg built onto the motherboard and only four slots for SIMMs. The above configurations are with 256k, 1meg, 2meg and 4meg SIMMs respectively. nate@casbah.acns.nwu.edu Nate Berggren ACNS Student Consultant Northwestern University

Regarding upgrading the IIsi memory. One other peice of data. The 2 meg simms are a bit hard to find and a bit over priced. 2 meg simms cost about $125 but 4 megs are $175. That is one of the reasons I am upgrading my IIsi to 17 meg rather than just 9. The above prices were from a recent Mac weekly magazine and of course are subject to change daily :-). Anyway, since you have to "toss" the chips already in a IIsi to upgrade, be sure you make the right choice in memory size. Personally, 5 meg just isn't enough for me, so I went to 17 megs (I know I will need a utility to access some of this memory in system 6, but system 7 will be out soon). Maybe, (but this is a big maybe), with virtual memory and system 7 5 megs might be a more viable configuration, but I still prefer real RAM to virtual memory any day. Dave Neff neff@hpvcfs1.HP.COM
