It sounds too good to be true, but it really works in many situations. Just install RAM Doubler software and you'll have twice as much RAM at your disposal for practically every application on your Mac's hard drive.
Although RAM Doubler does a little bit of memory compression, the main way it accomplishes memory expansion is by rerouting the inefficient memory allocation routines that Apple built into the original Macintosh ROMs. The program actually scans through the Mac's memory and harvests RAM that the Mac thinks is being used by the system or an application and makes it available to other apps.
I tried RAM Doubler on my 4 Mbyte Mac IIvx and was blown away to have my machine suddenly performing like an 8 Mbyte system. Although Connectix claims that RAM Doubler can make smaller systems run up to 10 percent more slowly, my Mac actually runs faster with it, because I'm not constantly quitting and restarting applications. It's priced at US$99, but I've seen it as low as $55 by mail order.
RAM Doubler: US$99. Connectix: (800) 950 5880, +1 (415) 571 5100.
