BBC Micro Ethernet Schematic V1.1
This is a revised version of the schematic. It has tie down of the data lines. Buffering of all control lines which are tied up and the buffer and bus transceiver are disabled when the 3.3v supply is missing. A short time ago the NRM had the Great Gathering and had six of Sir Nigel Gresley's A4 locomotives (including Mallard, which still has the steam locomotive speed record) all in one place. Two have now left but four still remain.
