I know it's really late in the game but I wanted to thank everyone for
their patient answers.

Alot has been going on in real life and had to take a long long break
from the newsgroups due to that, and as well as forgetting to check in.

I'm catching up on hundreds of messages on newsgroups and on IRC and in
the BBS scene.

I did order my components though, but haven't made much traction on the
project I posted about.

Someday.
