Well, since returning from home I now have 2 A1200's :-D. One is fully towered and has a BVision card, the other is a keyboard wedge with just the custom chips.
I gotta say, I love em' both...
@Xeron
I agreee totally - The wow factor of fitting the BVision was easily as big as the PPC card.
I reckon, however, my favourite upgrade was my first accelerator card :
Stock 2MB (chip only) A1200 -> Apollo 1240 (full 040@25MHz) + 16Mb fast
After fiddling with some settings (forcing various pointers / libraries into fast ram) and getting some 040 optimised libraries, the speed increase was awesome.
I ended up getting a BlizzPPC later, but should have gone for the 060 version (was too damn broke at the time). Ah well...
