    Mac IIvx questions

    Yeah I heard you can chip both the iivx and the quadra but since I got the quadra on its way I won't touch the mac ii..my understanding is that while the quadra only has one slot it's a PDS slot right?

    Cool. I'll worry about that later. First, the PRAM battery thing. I found one on Amazon but it says it's not rechargeable...does it need to be?

    Mac IIvx questions

    Good to know...the one in my iivx works fine it had some issues ejecting out fully but it was just full of dust. It ejects consistently fine now  Do you get a boost from the at&t DSP in the quadra 660av? In finder or in games?

    Tokyo racer I do have pictures on the trading post here. It's about a $20 difference between quadra 660av and a centris 650. (Quadra more) though the centris has a nubus rj45-coax eithernet card in it.

    A quadra 660av would be a big upgrade then, correct? (I may have a line on one)
