gEDA-dev: Thoughts on buses in gschem

[Steve Meier]

Ohh?

Hmmm a cpu with ethernet and ram....

I was thinking that a cool open source proof of concept project for
hierarchical buses would be a portable... low power consumption high
calculation power computer...

I was think of a supped up peda that had the power of a lap top but used
a head mounted display...
