I seem to recall Tyan once built a board that did OpenPIC, and I think Fry's (funky computer/consumer electronics store in Western US) carried it for a month or two. Just rumour? --=20 Ferret I will be switching my email addresses from @ferret.dyndns.org to @mail.aom.geek on or after September 1, 2001, but not until after Debian's servers include support. 'geek' is an OpenNIC TLD. See http://www.opennic.unrated.net for details about adding OpenNIC support to your computer, or ask your provider to add support to their name servers. --jho1yZJdad60DJr+ Content-Type: application/pgp-signature Content-Disposition: inline -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.0.6 (GNU/Linux) Comment: For info see http://www.gnupg.org iD8DBQE7aMrpe0DNEkH06HMRAsJiAKCYZghsVxiS5bhzJAX3zsJrYRIQhQCfQ5bu Qz9goNznUEBnYJuD2SQLe/c= =P9Ie -----END PGP SIGNATURE----- --jho1yZJdad60DJr+--
