Well, that makes sense. Speed Doubler doesn't do much for 68k macs (ok, it does make an attempt at multithreading - like emptying the trash can in the background, copying files in the background, etc. I guess it also has that "smart copy" feature...). It's biggest benefit is for low end PowerPC Macs. Speed Doubler has a more efficient 68040 emulation routine than earlier PowerPCs/System 7/OS 8.1. System 7 and OS 8.0/1, I believe, emulate a 68020 (for compatibility) on PowerPC. And they do it inefficiently. Installing Speed Doubler on something like a 61xx, 71x0, 81x0, 62xx, 6300, LC52xx, LC53xx, 5300, 1400, or 2300 should increase the speed of 68k apps when running System 7.x or OS 8 prior to 8.5. Some say that the difference is dramatic. I can't see any reason why you need to run Speed Doubler on a IIci. Unless, of course, you like painstakingly slow file copies. OS 8.5 has an updated 68k emulator that implements a 68LC040 (IIRC) and is far faster than it's predecessors. On macs with this OS, the benefit of Speed Doubler is essentially nil. In any case, your OS choice is as subjective as your choice of favorite color. It's no surprise that system 7.6.1 is faster than OS 8.5. I choose 8.6 because I can live with the relatively slower boot times, app launch times, and certain finder operations. OTOH, I find myself MUCH more happy with a multithreaded operating system, pretty icons, menu clicks that you don't have to hold down, pop-up windows, spring loaded folders, Apple-Delete trashing of files, and the ability to run modern applications. OTOOH, I don't go to OS 9 because I'm happy with the 8.6 feature set and don't want the added speed hit that OS 9 would bring. So, picking an OS is like picking a toothbrush ;-) Get the one that does the job and feels best. Whether it's a new-fangled "sonic" toothbrush or one made of wood, it still cleans your teeth. Or something. I'm tired... ;-) Peace, Drew -- Author of ClassicStumbler email: <[EMAIL PROTECTED]> web: <http://homepage.mac.com/alk/> Want to know if your neighbor has Wi-Fi?
