Well, I now have it on my 500mhz iBook, and it's very slow. On a system dialog it claims I'm running at 285mhz, though it feels more like 200 (or less).
Took off Media Player, movie-whatchmacallit -- and them dang card games which you can never win at. (Pinball play was nearly impossible.)
Seems okay for text programs and, for one data unit only, I'm running Folding@Home. That is as slow as drying paint, but I got to write a quick batch file to start it up from the command prompt. I really enjoyed batch: simple-'n'-easy programming.
Only games I can tolerate are Masque slot machines and video poker. All the others I listed tax the software emulator.
Still gonna get that real laptop.
