i have just bought my first mac. its an iMac G3 running @ 333Mhz with 32mb ram. i opened it the day i got it and it takes 144pin so dimms. is this any so-dimms? i found a place here in ireland selling pc 100 and pc 133 so dimms quite cheap (About 50EUR for 256MB). would this work? i have to find out the height of these. i found out that the external dimm socket will take memory up to 2" heigh and the internal one will only take 1.5" heigh memory. if this works, OSX here i come! Thanks.
