[connect FPGA PDP-11 to Ethernet]
So there too is a bit of a challenge - which
situation to build the VHDL for?
ENC28J60 Stand-Alone Ethernet Controller with SPI
Interface:
http://www.microchip.com/wwwproducts/Devices.aspx?dDocName=en022889 Just found an
other thing in that category: W5300 from
http://www.wiznet.co.kr/
It is used on this
http://homepage.mac.com/dgcx/pdp10x/ FPGA PDP-10.
Can you get to raw Ethernet frames on the W5300? I haven't (yet) designed with it,
but it seems it does IP only, and doesn't expose raw Ethernet to the host interface.
That would make it a poor choice for machines that often want to run, say, DECnet.
