So now for only $60 and a lot of my time (not worth a whole lot), my sister has a fairly fast PC (800 MHz) that she can use for email and web surfing. She had been trying to use my first Mac...an old Performa 6200 (75MHz). It just plain flat wouldn't work...The browser's home page would never finish loading when trying to connect to the web.
Well, at least you learned some things from the experience, yes? 
I hate to be the bearer of bad tidings, but 800 MHz is not a fairly fast PC; in Mac terms, it's about up there with a PowerPC 604-based system, before the days of the G3. Systems like this usually sell for $5-$15. I saw an 880 MHz system at a thrift store recently (I'm in the market for a new PC for Shelly); they wanted $25 for it, and I didn't take it.
