Other > than the fact it's way cool just to have it.... Bingo....well, quasi-bingo. I agree that there isn't much yet to use up 7 meg. VM would presumably be more useful to people with only a couple meg. There are huge memory applications forthcoming, however. A 4000X4000 24-bit plane image (good enough to record with sub-film grain resolution onto 70 mm film, I believe) takes up 48 megabytes. Of course you'll want to keep it entirely in RAM -- accessing it via VM into a few meg would take an excruciatingly long time. You'll want an undo buffer, too. -- -- uunet!sugar!karl | "Woof!" -- free Usenet access: (713) 438-5018
