Apologies if this has been discussed before, I didn't expect to have
anything to do with 10BaseT (twisted-pair Ethernet) until very recently...
Are there any PC and/or AT Ethernet interfaces which have a 10BaseT
transceiver built in? Note, not a normal Ethernet transceiver, but
a 10BaseT twisted-pair transceiver.

The 3Com card is called the 3C503-TP, and indeed software written for the venerable thinnet-compatible 3C503 works with it just fine (this includes at least 6 drivers I have tried, including the Clarkson packet driver). The Cabletron card that I have is for the AT only, and is called the DNI E3010. It comes with a packet-driver driver (?) which works well. It's worth noting that each card works with the other manufacturer's 10Base-T repeater, too. I'm sure there are many other manufacturers of similar cards. Onward to commodity pricing. - RL "Bob" Morgan Networking Systems Stanford

Yes, this is also the story I've been getting by mail. Thanks to everybody who sent info; the basic conclusion is that although they may not yet be as widely publicized as the older boards, boards with builtin 10BaseT are available from almost everyone at prices comparable to non-10BaseT boards. -- TCP/IP: handling tomorrow's loads today |Henry Spencer at U of Toronto Zoology OSI: handling yesterday's loads tomorrow| henry@zoo.toronto.edu utzoo!henry

We have been buying the Western Digital 8-bit product, I've spaced the model number, which has a 15-pin and an RJ45 on the back. Seems to work fine. -- Walt Haas haas@ski.utah.edu

There are currently(to my memory) several vendors of 10BASET boards. They are: Western Digital 3Com Tiara Digital Ungerman Bass Since we're one of the founders of 10BaseT, we've had to test the products. They all seemed to pass all tests with PC/NFS, Netware, 3+, PC/TCP software. Note that our group is the networking group for SynOptics, and as a result, is often asked to test these things before they're certified " " for use with our products. I speak neither for SynOptics, or myself. I've simply wanted to help get folks onto what I feel is a much more flexible, and more effecient networking strategy.. -- Steven C.

Add to this list Hewlett-Packard, whose Ms. Thayer chairs the IEEE committee and who, along with others *rejected* the first Synoptics proposal - note that there is NO SUCH THING as a concentrator in the specs. And don't forget AT&T's StarLAN 10, which won the LAN Magazine Drag Race and subsequently the Ethernet Product of 1989. Historically, there have been roughly six major proposals for the standard: AUI1 H-P 2-pair MAU-MAU with AUI Interface with MPR AUI2 Synoptics concentrator without retiming Sync Chipcom Synchronous Manchester coding AUI/Coax 3COM/DEC Pair-tamer extension of 10BASE2 Mod Man David Sys Asymmetric MAU's different at each end OQPK Rypinski QPSK (quickly rejected) Until recently, Synoptics and Cabletron both offered incompatible equipment with any other vendor's - problems with Receive Equalization and voltage levels with Synoptics (along with the use of concentrator technology) and Idle Signal use, respectively. I understand that they now support *true* interoperable 10BASET products (incompatible with their previous line). This is one of the problems of being 'first to market/first to buy'. Also, be aware that FCC registration and actual FCC compliance of Rack style MPR's are two different things - I sincerely doubt that any Rack unit, although stickered and given an FCC number, would actually pass the stringent tests in the real world. -- +--------------------------------------------------------------------------+ | Carlo Milono | | Personal: netcom!cmilono@apple.com or apple!netcom!cmilono | |"Sometimes I think the surest sign that intelligent life exists elsewhere | | in the universe is that none of it has tried to contact us."
