That would be great. Yes I'd love them soon than later so I can get to work.

This is where the community would need to come in. You're talking about
territory way outside my knowledge. The point of this project, for me,
is to allow for full restoration of these old devices without removing
them from circulation. Some say there are so many of them out there that
it's okay. Our community is far more niche than the commodore side of
things. If a board has extensive trace damage from leaking caps and
other issues, I'd love if a board could be replaced and the working
components populated on the new board. I know it's alot, but it's being
done all the time in other communities like the C64. Hell, you can order
a board of all revisions and a choice of colors. Some youtubers have
managed to make brand new c64's with off-the-shelf components and
homebrew replacement chips.

And creating boards that accept all the old components but modified with
improvements I'm totally open to - but it's secondary far in the future
unless the community jumps on the bandwagon.
