Old world macs with bandit / copperhead chipset can do up to 50MHz  
but not all machines are stable at that speed, a common symptom is  
RAM getting flaky. You may need modules faster than 70ns, there's a  
small chance the board won't run properly at 50MHz at all. G3s use a  
completely different chipset that supports higher bus speeds.

No, IIRC they all shipped with graphics cards and even if they didn't  
you could always add one.
Those machines were ordinary macs, nothing like the Xserve. What made  
them 'workgroup servers' was the software and hardware options they  
came with.

have fun
