This is probably of more interest to CPU upgrade card manufacturers. There are a few 040 cards out there, if the user swapped the voltage regulator, they could upgrade to 060...but most people get the CPU with the card.
I was very disappointed by my A1200/060. Though I admit the 060 was a lot faster than the 030 it replaced....its just that the AGA graphics were such a horrible bottleneck....now we have pci busboards...these pci solutions are better than AGA, but, the real advantage, even to these pci buses, is that they accept cheap pci cards...not that they can pump high throughputs of video, as, they are still limited by the pci-to-amiga bridge.....
Long story short, heck ya, I'd buy an 060 if I was still using a classic amiga, but I wouldn't expect it to be anything but a dinky slow 'classic'
I mean, given that any classic amiga is 'retro' computing...isn't any retro year chosen, a valid choice?
Why not pull out whatever acclerator you have, like the 030, and go stock? Go back a few years more in the quest for nostalgia and that retro feeling....about as valid as buying an 060...
any thoughts?
