I got a 7200/120Mhz mac and recently purchased a G3 400Mhz/1M CPU upgrade (works with the 7200/7215/8200/ WGS 7250) - heh its my MIDI Mac (well wannabe - because I have yet used it - been busy with other stuff).
Btw, I am about to sell my iMac G3 all in one 500Mhz with 1gig of RAM / OSX 10.3 / OS9.2 dual boot if someone is interested $100 plus shipping (only USA), and will probably sell my A2500 too - but that is a different post.
