Sorry to say, our inventory of hardware drivers represents enough of our competitive advantage that we must value it highly. We sell the executable package for $400 quantity 1, $175/copy for Site Licenses for between 20 & 49 copies, less per copy for larger quantities. Programming libraries (including sockets) are available for Microsoft C. We have an academic discount, too. Call us, or send us a USMail address and we'll send out the price list, etc. Regarding the underlying technical issues, the 3C501 is an old design, doomed to be slow on loaded nets and with fast hosts because of its 1-buffer architecture. It also has trouble with transceivers which generate heartbeat (like the DEC DELNI). Any other network card we support is faster than the 3C501 (I'm not sure it is the slowest available, but it is the slowest I have used). The 3C503 is definitely better (although not fastest, in my opinion). Other "3rd generation" cards with a similar architecture include the Western Digital WD8003, the MICOM-Interlan NI5210, the Univation NC-516, the Ungermann-Bass PC-NIC and the National Semiconductor/Novell card. Our driver for the 3C503 is about average among this group. I don't know how other developers rank it. James VanBokkelen FTP Software Inc. (617) 868-4878
