I would like to make my own PhoneNET box. Not because I think it will be
cheaper or better, but because I think it would be fun to do.

I know that PhoneNET evolved from BMUGNET. In the BMUG FALL 1985 NEWSLETTER
diagrams of RevA and RevB of BMUGNET are given. And in the BMUG SPRING 1986
NEWSLETTER I read that Farallon distributes a PhoneNET box, which is "basically
compatible with the circuit in the PhoneNET board (kits and assembled versions)
and the BMUGNET RevC designs." And a diagram of (by now patented?) PhoneNET
is given

So can someone tell me what the BMUGNET RevC design looks like, and where it
differs from a PhoneNET box? This information is probably printed in the
BMUG 1985/86 WINTER NEWSLETTER, which I don't have. Especially I would like
to know what transformer is used.

Also, what about the legalities? If a design is printed in a publication,
can you make it for yourself as long as don't sell it? (No, I don't want to
sell it, I don't even want to use it: I only have one Mac :-).

SVP mail me, I'll summarise for the net.
