I will be purchasing a Mac system in the near future and would appreciate some advice. Money is somewhat of an issue: I have about $3200 in grant money to spend, and am willing to kick in somewhere around $2000 of my own (i.e. would like to spend less than $5500 on the system). I have access to educationally discounted hardware (MIT) That said, here are my questions: 1) CPU Obvious first question: should I buy a IIcx or a IIci? I have used a IIcx, but not a IIci. Those of you who have used both, how noticable is the difference in speed in everyday use? The price difference is fairly substantial. At MIT, a stripped IIcx is $2995 + tx, while a IIci runs for $4185 + tx. Is there a cheaper source for these CPUs? 2) Memory I think that 5MB is about right. What is the best source for memory? I have never installed a SIMM, how tough is it? (I have installed a MacSnap board on my 512e, is it easier/harder than this task?) Does self-installation void the warantee? 3) Display I have been working with the apple 13 inch color display, and think that it is suitable for my needs. However it IS quite expensive. It also has Apples foolish 90 day warrantee - how likely are monitors to break after the first 90 days? How do the third party monitors of a similar size compare in picture quality (I know that they are substantially cheaper). Any suggestions on alternatives to these displays? How slow is the IIci when driving a 13 inch display with its built in card in 1 and 8 bit modes? What are the relative merits of apple and 3rd party cards (no, I don't think that I need 24 bits at this time)? 4) Hard Drive I currently have an external Supermac Dataframe XP30, which I suppose that I could continue to use (haven't filled it yet). I seem to recall that different interleafing is recommended for the Mac Plus and II series hard drives - how does this work (I know little about hard drives, is the interleaf specified in the format or is it hardwired?) How much difference in system performance would it make to get a faster internal drive? 5. Keyboard I am presently using and happy with my datadesk 101. Unfortunatly it is not an ADB device. Is there any way to convert it to one? If not, what do people recommend? I haven't used the apple extended keyboard, is it worth an extra $40 (not to mention the fact that the datadesk has a 2 year warrantee...) Comments on any/all of these would be greatly appreciated! -- ***************************************************************************** * David Resnick dresnick@athena.mit.edu * * "Smoking-Think of it as evolution in action" * *****************************************************************************

If you decide to upgrade (to 8, 20, or 32), you'll be stuck with 4 basically useless 256K SIMMs (if you go to 32, you'll have 4 1MB SIMMs, but those are still pretty useful). Given virtual memory in System 7.0, 4MB should be fine. Given the price of memory these days, 8MB should be inexpensive enough to go with. -- David Elliott dce@smsc.sony.com | ...!{uunet,mips}!sonyusa!dce (408)944-4073 "...it becomes natural, like a third sense." -- Homer Simpson

Given the >price of memory these days, 8MB should be inexpensive enough to go >with. 5MB is the configuration one gets after adding 4 1MB SIMMS to the 1MB (4 256K SIMMS) that comes with two of the three standard configurations of the IIci, IIcx, IIx, and SE/30. It's much cheaper to do this than to buy the 4MB RAM/80MB hard disk configurations that Apple sells, which adds $1400 to the cost, even at University of Minnesota educational prices. It's much cheaper to buy the RAM separately. You could get a 105MB Quantum hard disk and 4MB additional RAM and still save $400-500. On the other hand, the 1MB RAM/40MB hard disk configurations typically add only $300-$425 ($300 for the SE/30, $425 for the IIci) to the cost, which is well worth it, since the Quantum 40MB internals tend to sell for $450 or so (but with a better warranty). I'll never understand how Apple determines its price structuring. -- Steve Kanefsky kanefsky@umn-cs.cs.umn.edu

Unless you feel the "need for speed", I'd go with the IIcx. Except for some
types of number crunching, you won't really save that much time. Also - the
IIci is having problems with some software and others won't run on it - yet.
What constitutes "enough speed" anyway?

5 megs is plenty - any second source of 100 ns memory should do (typically
$85/meg). It's VERY easy to install.

I use and am happy with the Magnavox Multisync 13" at about $550 discounted.

For 24 bit - you are better off with the RasterOps 264 (Apple doesn't have a 24
bit yet - I don't believe).

The interleave is 1:1 on the MacII and (I think) 1:3 on the Plus. I would
reccomend any of the 45 meg. cartridge drives.

The Apple extended keyboard is okay. may be a little more expensive that others
but not that much - I'd go with it.
