RAM is your problem. 8 MB is almost completely unusable on a PowerPC. The 601s are bad, the 603s are horrendous, but the 604s and 603e's are passable.
RAM Doubler doesn't help as much as you'd think. It really needs more physical RAM to become useful. (RAM Doubler is *NOT* a 'hard drive caching' virtual memory app, it compresses the contents of your physical RAM. The less RAM you have, the more compression it needs to apply. And some apps are basically 'incompressible', so regardless of the fact that it says it is 'reporting' 24 MB of RAM, you don't actually have that available.)
You may want to look into RAM Charger, too. I have an 8 MB PowerBook 5300, and with RAM Charger, RAM Doubler, and Speed Doubler, 7.6.1 is just barely usable. (7.5.x isn't much better.)
RAM is really what you need. The 7200 at least takes a nice standard type of desktop memory.
