Weird Science : OSX on an older mac

    Okay folks some advice needed- Ive just installed osx 2.0 (i think) on an old Blue & white g3 (300mhz with 640mb of ram) which has been lying dormant .
    ive got a 2nd HDD in there & i'm hopefully gonnna load it with tunes & use it as an itunes jukebox type thingy- fair enuff.
    Ive also got Macmame installed & i'd love to load up a stack of retro games to play too BUT it (macMAME) seems to be running really slowly even on simple enough games from the Mid 1980's
    ive checked the cpu load when running macmame & its something like 25 or 30% which i wouldnt have thought was a problem
    is there any OS "Streamlining" or unnecessary shyte i can turn off to improve the performance of the computer especially for the emulator.
    Or Is there a way of changing the amount of Ram commited to a program??
    i know you could do this in os9 etc but im not really familar with Macs/ Osx at all (my main computer is a PC (oops) )

    OS9 memory management was very primitive - assigning memory to programs is very backwards thinking these days. :) A modern OS will give each program memory as it asks for it and will swap other programmes to disk if there isn't enough physical memory available. 640MB of RAM is more than enough memory for what you want to do anyway.

    I've run both MAME and a SNES emulator on my G3-500 iBook with 384MB of RAM in the past without any problems.

    Surely he meant to say 64mb?!

    no its 640mb
    3 sticks of 128mb & 1 of 256.
    to be honest i didnt expect any probs running Mac mame but there you go. ive run several resource hungry apps on this computer before (albeit under os9)with no probs

    Ah, then I guess having OS X on a 300mhz processor is taking it's toll.

    The latest versions of OS X (10.3 Panther and 10.4 Tiger) run faster than 10.2 on the same hardware so updating the OS might be your better option.
    You could also try following the advise at http://www.thexlab.com/faqs/performance.html

    Best of luck.

    Definitely upgrade it to Mac OS X 10.3 or 10.4 (it sounds like you're running 10.2 at the moment. You should see a big improvement, and obviously bear in mind that it's a 300Mhz (!!!) computer, but it should still be fine for most things. Just don't try to edit a movie on it like. ;)

    thanks everyone, its up & running (fairly)okay Under osx 10.3-
    although on closer inspection
    i may have had a stick of incompatible ram in there too theres 64mb less in there now but it seems to be running smoother so thanks again.

    Yep, it'll more or less get better the higher you go. Early OS-Xs were extremely dependant on Altivec, for some reason.
