Al just recently put this up on Bitsavers, November 1974 drawings for the first 2.94MHz Ethernet transceiver:

Neat to see the 15 pin AUI to Thicknet transceiver (well, a lower bandwidth version of the 10MHz ones I grew up with) drawn out so clearly. Also shows something I've never seen in real life, an "Ethernet Dummy Transceiver" which is, I guess, something like a two-port DELNI ? (obviously showing my DEC introduction to AUI Ethernet there.)
