Bumgarner) Newsgroups: comp.sys.mac Subject: Re: Virtual memory init Message-ID: Date: 19 Jan 89 04:44:36 GMT Organization: Carnegie Mellon, Pittsburgh, PA Lines: 23 Even when real memory comes down in price, there will still be a place for the virtual memory INIT>.. System 7.0 should be able to deal with 32bit addressing, meaning that the effective limit of memory becomes 1 gigabyte. Currently the INIT can only deal with up to an 8Meg swap space because of the system software, not itself. It will be a long time before the price of 4 meg SIMMS (for a 16 meg Mac II) will be as inexpensive as simply setting the INIT to a 16 meg swap space... and if you need more memory, clear a little more space on the hard drive. One might think that no one will ever need that much memory-- wrong. Have you ever tried to process a good-sized image in ImageStudio@300 DPI? w/undo enabled? can take way more than 8 megs-- an 8X10 image at 300 DPI w/undo takes a little over 14 megabytes of RAM. Using the virtual memory INIT not only gives you the ability to attempt processing images that large, but to be able to do it under MultiFinder! Other applications need loads of memory, or at least would be happy w/a lot more than allocated to them; HyperCard, FullWrite Professional, MacNet.... b.bum wb1j+@andrew.mcu.edu
