I am completely ignorant when it comes to the nitty-gritty technology side. I was just thinking of it like the Pentiums being an engine and the Amigas being cars - to some extent you can fit different engines in cars with some sodding around and get a perhaps more powerful car as a result.
I wish I'd gone for one of Jens' 1230/56 cards to start with but I was just too tight. Serves me right.
Oh well, who knows... perhaps a few more years down the line another Amiga tech sage will amaze us all with a 100mhz+ accelerator!!!!
