The 501 can't walk and chew gum at the same time. Some folks might say it has trouble doing either alone 8-). You are correct that the 503 is a very different board. Back when the 501 was the only low-end card that 3Com made, I tried very hard to get programming documentation for it. 3Com de- clined. I was later told by a 3Com employee that they were ashamed of the card and would never release the programming docs, especially since the 503 came out and was a much cleaner card. You can get either 503's or 509's for under $125 via mail order (look in the back of PC Magazine). I'd suggest you get one of those and spend your program- ming time fixing things you can't easily buy. If you absolutely *must* do a 501 driver, you may find a packet driver for it that you can use to reverse-engineer the programming interface. Note that BSDI's offering includes a 3C501 driver, which the man page says is seriously not recommended due to major performance problems.
