I’m the proud recipient of a Paleolithic era iMac with 128 meg Ram (circa 1993) which I’m going to use for learning soft for a kindergartner.
Do you know how much more Ram I can add this thing?
I’m sure he’ll need at least a model# to do any reserch. 
Yeah but I’ve been meaning to post this question all weekend and now that I’m at work, where the iMac is not, I finally remembered.
I thought I would at least get the question asked before more of my Paleolithic synapses break down; if more is needed I can get that later. I just hope I remember to check the forum again. ;D
you say 1993 but the iMac was not avaliable untill 1998 so obviously its either not an iMac or you got the year wrong.
if you get me the serial number I can tell you everything about the mac.
The serial number will be listed on the machine (iMacs on the bottom) or in the Apple System Profiler (avaliabe in the apple menu in Mac OS 9) or if it has OS X you can click the apple menu and choose “about this mac” and click more info and that will bring up the apple system profiler
or just tell me the model and processor speed (example PowerMac 75Mhz or iMac 233Mhz)
(Edited by mac to include OS X info)
I’m 99% sure on the iMac part and much less so on the year. Definatley OS 9.
I’ll post the seriel number when I get home from work.
Thanks Mac.
ok if its an iMac then turn the machine updise down and between the two front feet will be the serial number
iMac for sure
Serial # YM0352G5JWQ
your iMac is the model released in Summer of 2000
It can hold up to 1GB of RAM It uses PC100 DIMMs (you can use PC133 if you cant find PC100)
Upgrading the RAM is easy there is an access door on the bottom of the machine that opens to reveal the RAM bays
exact install instructions are in the Knowledge base article below:

if you have any other questions feel free to ask im here to support the Mac users on the forum 
Thanks Mac,
This is a much newer machine than I was told.
On more quick question. If I can’t find PC100 can I mix PC133 with the existing ram or should I replace the old ram and keep it all the same?
yes you can mix PC100 and PC133 ram in the system. All the system does is underclock the PC133 RAM to run at PC100 speed (which is all the computer can use anyway)
You can find PC133 at most computer stores like Best Buy, Staples, Circut city etc.
Yes it is a good Machine The Processor speed is between 400-500Mhz (PowerPC G3) and is equal to about a 800Mhz - 900Mhz Pentium III or Athlon
Drhayden, you just now found that? ;D
Found What Mac?
Or Am I Getting Old and Don’t Know What You Mean By-You Just Now Found That? ???
Its really is surprising (to me) how well programs run even with the current level of ram. But this is my first real experience with anything Mac.
Thanks again for all your advice.
128MB of RAM is really more than enough to run Mac OS 9 the only reason you need to updrade the RAM Is if:
a) You are going to install OS X (in which case you need to update the firmware)
OR
b) the programs you are running require more RAM
I used a PowerMac 7200 up until 2001 it has a 120Mhz Processor and only 32MB of RAM and yet it ran great in OS 9 for basic web surfing/ email / word processing tasks
if you are going to keep OS 9 make sure you run at least version 9.1 as it has many improvements over 9.0.4
I ran the software update utility last night but I’m still at 9.0.4. I did get some other updates including the Carbon Library (seems like a good thing), but how do I update the OS?
Sorry for such basic questions but using a Mac feels like the first time I used an HP calculator - it looks the same, but where’s the equal key?
Just go here and download the updater and run it simple as that
Wow - a built in donwload manager :o Very nice.
I’ve updated to 9.2.2. Is there anything else I should do?
you have the most current version of the Classic Mac OS. (9.2.2) so as long as it does what you need then just enjoy!
