>An 8080 could not do it and graphics has little to do with it.
I make this claim for custom IC design. I say it is posible for two reasons
but not practical. The first reasion is based on the IDEA that PCB layout
and IC layout are much the same so macro-cells could developed
as basic blocks, as well as graphic blocks to display the layout.The second
factor is this design is not going for speed in both layout or gate delays.
A resonable amount external memory is called a 8 inch floppy.
I don't want to develop the latest generation CPU but something
that fits with 8080 -- 8088 layouts. I don't want to forget about
system bootstrapping something is easly forgotton when doing

P&R is mostly sorting is my guess. However my designs view point for
is being able to keep the computer system capable of bootstaping itself.
Looking at the
latest version of red-hat I find it hard to do any real development work
is becoming too interconnected with every thing else.
PS. I like small computers -- I just use big ones like PC's to play games.
12 to 18 bits to me is a nice sized machine.
