Hi Charles,

It is possible to hook an ethernet interface to the BBC, all you need is
an 8-bit ethernet controller. The most likely possibility is the Crystal
Semiconductors CS8900A (http://www.cirrus.com/en/products/pro/detail/P46.
html) or the Realtec Semiconductors RTL8019AS (http://www.ethernut.de/pdf
/8019asds.pdf). I believe that the RTL8019AS can use interrupts in 8-bit
mode, while the CS8900A can't.

Check http://www.embeddedethernet.com, http://www.ethernut.de/, http://ww
w.6502.org/ or just search the internet for 'embedded ethernet' and you'l
l get plenty of examples and resources.

I've been thinking about making an Econet-Ethernet bridge, based on one o
f these ethernet controllers, a 65C02, an econet interface and some RAM &
 ROM. Shouldn't be too difficult, especially with the ready-made ethernet
 module available at http://www.embeddedethernet.com/. If anyone is inter
ested in developing hardware or software (TCP/IP stack etc.) please let m
e know :-)


Regards,
Eelco

Hi...

This has probably been asked before, but has anyone ever thought of/succe
eded in creating an PC econet interface? or even a BBC -> ethernet i/f? w
ould have to be something simple like IPX as the tcpip stack might not be
 feasible..

I know sweet bugger all about econet, but am bored with current pc stuff
:D and wanna try something new.

My B hasnt got any econet h/w atm, can I retrofit it? what would I need e
tc...

any ideas appreciated
