Chris, will you be publishing your thesis?

I think this is because of the limited number of people with hardware
backgrounds.  I mean it is fine because when it comes down to it, this is
a list to support people writing games etc.  Generally not much hardware
is required.

I completely agree.  After working with the chip some and being tormented
by the few details the stella programmers guide gives you, I would _love_
to go over the schematics(buggy or not) for a couple hours.

Well, I would like to see it :)

Well this would be the only way to make a truely _portable_ vcs.  Wether
you do it for marketing, or just for the fun of it, it still requires the
integration of the chipset.  I've considered it on and off, but I've
realised that as a hobby, I can't take on projects that are too big as
I'll eventually become distracted and forget about it.  That's what
happened to my bankswitched sram cart I was working on about a year
ago.(very similar to cuttle cart, but using a serial port, and not
including the supercharger audio support.)

In any case, I for one would like to offer a note of encouragement, for
both Chris, and Kevin.
