We sell versions of our PC/TCP product for the 3Com 3C505.  Our drivers
use 3Com's on-board ROM, and don't load any of their own code onto the
board.  We ship the code with a TCP window of 1024, same as the 3C501.

I think that Network Research did a version of their PC product, which 
does actually load code onto the board.  I've never used it.

3Com should be willing to sell you a "3L" library for the 3C505, probably
for $995, which contains source for an example driver.  I don't think
their driver loads code onto the board, but I'm not sure.

Driving the board has a number of tricky timing issues, which would be best
resolved by looking at someone else's code.  Try 3Com again...
