I have a nice Quadra 840 A/V running OS 8.1 very well with 52MB of built in RAM & upgraded VRM.
If your interested I can fire it up and give more details.
How Big is the hard drive and how much money for the unit? How much VRAM is in the unit?
Hard drive is 700MB. Not sure about VRAM but I would say it's maxed or close because I can get millions of colors at 640X480 resolution.
How much money ? Make me an offer........
FedEx shipping it would cost about $12-20.00 depending where you are in the US.
