OK, I need some advice. It's been a while. I've got two computers. One is a little old the other is a very old (in computer terms). It's a 10.5.8 PowerMac with 1.5 gigs of memory. It's so slow these days I have trouble doing crossword puzzles. Is there any sense in trying to boost its memory or any other upgrade I can make to make it run smoother that makes any sense? Or should I, as I expect, purchase a new one? And if so, what kind of new one? It's been a while. I have a newer large screen computer at another site that still works just fine so I haven't been desperate. But .... Jim taylor
