For me this is an option. I'd like to have ethernet, but I don't need
it on board. You can put ethernet on the I/O bus, since it doesn't need
high bandwidth.

Fast graphics is a must for me. It is one of the reasons why I'd buy
such a thing. I think that an onboard dumb frame buffer is the best
solution. Using a conventional ISA VGA card will be slower (probably
even with accelerator), and VESA local bus or some other interface for
high performance graphics cards will be difficult. I think we should
put our brains into a clean design, not into workarounds for intel

I think we need some kind of I/O bus. ISA is nice for people who
already have ISA cards or prefer to buy hardware instead of designing
it. A simple proprietary bus may be better for the hardware gurus (and
chaeper). I am not sure what I would prefer, but I am leaning more
towards the ISA bus. I would keep the number of slots small, however
(max. 3).

But this will be the most fun.

This could be a problem. But I need a new monitor anyway :-)
