Given that at least one person I know has been refused when he tried to 
buy 3C501s, and sold 3C503s instead, why are you going to write a new
driver for that board?  I don't know when it will go out of production,
but even the weight of existing software won't keep it alive forever.

The MIT and CMU distributions of PC-IP both contain public-domain 3C501
drivers in C.  The only programming manual I have ever seen is passed
from hand to hand as a treasure, and is dated 1983.  You could try getting
it from 3Com, but I know people who haven't succeeded.
