On a Mac IIsi running System 7, whenever I choose "About This Macintosh..." and add up all of the memory in use and unused, it always comes out to about 350k less than total memory. This is with 5 meg or 9 meg (just upgraded), with or without extensions off, and even immediately after startup with extensions off and no nothing opened (except the About This Macintosh... thing). Does anyone know what's the scoop? Is this a FAQ I missed? (I saw the recent thread about huge memory "losses", but this is different.) Thanks for any info, and apologies if this has been discussed to death already. Ken Kreshtool (kik@wjh12.harvard.edu)

Actually it's a clever and sneaky hack by the guy at Apple who did VM, his Mac doesn't actually have any RAM in it, he just sneaks 350k odd of space out of everyone elses ..... :-) Actually, it's the space used by the "About this Macintosh ..." dialog :-) well really I don't know .... maybe rounding between 1K and 1024 somewhere Paul -- Paul Campbell UUCP: ..!mtxinu!taniwha!paul AppleLink: CAMPBELL.P Tom Metzger's White Ayrian Resistance has been enjoined to stop selling Nazi Bart Simpson t-shirts - Tom of course got it wrong, Bart is yellow, not white.
