1)if get my hands. on a PowerPC 603e @ 160-240 MHz ,is it advisable to install it in the trap door expansion slot??? and will there be space to attach a fast memory and a graphics card in the same space . I always loved the idea of a keyboard+processor+memory+media drives all in one unit..i was thinking of rippng out the cooling fan of my old laptop and putting it into the miggy
I am not sure about this, but i think it will be hard to fit it while at the same time keeping the casing on. I know you can fit a 68k accelrator easily, but i think it will be problematic for a ppc one.
2)is the shark hardware acelerator better than the power pc?
The announced specs are indeed a whole lot better, but it has not been released yet and who knows if it will ever materialize.
3)is there a USB edvice availible for the miggy 1200?
Amigakit sells USB controllers:

And who knows, maybe a cheaper and much better ppc card/box has been released by then. The only one who have a classic a1200 with OS4 is some very few beta testers. So right now, the only platform supporting OS4 for end users is the AmigaONE. So if you want OS4 now, then you will to buy an AmigaONE by second hand.
