To all 3COM 3C501 users,
I have a 3Com 3C505 PC bus-to-ethernet adapter, which is the
follow-on product to the venerable 3C501. Nice things like PCIP,
NCSA Telnet, DECnet/DOS, PCNFS, and netwatch run on the 3C501, but nothing
for the 3C505 yet (is this still the case?).
The 3C505 is supposed to be much better, with more buffering and
a higher throughput rating.
Question: does anyone have any documentation on this new card which
would allow me to adapt PCIP or these other products for it? 3COM has
been inexplicably uncooperative..
I need to have documentation which would allow the writing of a
driver for it, so device registers are really what I'm after.
-David

The 3C505 is actually almost as venerable as the 3C501. It was intended not as a follow-on product but as an entry into a slightly different market. The 3C505 is a smart board with an 80186 on it, and you can download code to it or use it as a dumb board. It tends to run like a dog (with one leg). It's a pain to use as either a smart or dumb board, so there aren't lots of pieces of software that support it. The only TCP/IP implementations for it that I can think of offhand are NRC's Fusion and FTP Software's PC/TCP. If you want *real* new 3COM boards, check out the 3C503 (real successor to the 3C501) and 3C523 (Microchannel board). You can probably get lower prices, better performance and wider software support from the Western Digital WD8003 and Micom-Interlan NI5210, though. - john romkey UUCP: romkey@asylum.uucp ARPA: romkey@xx.lcs.mit.edu ...!ames!acornrc!asylum!romkey Telephone: (415) 594-9268

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... James VanBokkelen FTP Software Inc.

I don't have the 3C505 specs, but a user contributed a driver for the 3C505 for NCSA Telnet version 2.1. I need a volunteer to update it for version 2.2. Check out the 3C503 also, it has better price-performance because it is less expensive. Does the software you want to run take advantage of the extra hardware on the 3C505? NCSA Telnet isn't built that way. Tim Krauskopf timk@ncsa.uiuc.edu (ARPA) National Center for Supercomputing Applications (NCSA) University of Illinois, Urbana-Champaign
