Could be. Its an old one, whatever. Actually I think that might be it!

Sounds likely, though "a pile" might be stretching it.

Ahh.. I might be trying to persuade you to invent the wheel you already
built then. To convert a beeb B/Master into a dedicated two-port router
(its more than a bridge.)

IP-Over-Econet bridged to Econet-over-Ethernet and IP over ethernet vs
Econet tunnels over IP.

Possibilities - hang a beeb off the Linux server (which of course would
need to be an econet server using econet over ethernet, or econet over
IP, as far as the bridge, which would convert to standard econet, or IP
over econet as applicable (doesn't that make it sound easy?)

Its either that or put an econet interface in the linux box, and these
days, what with PCI being scrapped, and PCI-Express<spit> being thrust
upon us, could be quite a mission.

Hmm.. There are microcontrollers with USB stuff on them.. I'm not that
familiar myself, of course....


Cheers!
