I have a "TRUST-Etherpocket"-adaptor with a twisted-pair and a thin-ethernet-coax connector which connects to the parallel port of my notebook. The readme of the Dos/Windows drivers (Win3.11 works fine) says that it is an "Accton EN 2209". On the device there are four LEDs (Power, TX/RX, TP /Link, Coax) and it comes with a small spiral cable which can draw power from a PS/2 mini-DIN Socket thus eliminating the need of an external AC-power adaptor.
Here are pictures of both sides of the adaptor's circuit-board which may give a lot more information than my explanations. (Specs follow below). The main chip on the circuit-board (below the metal-strip) is labeled "EN 50903, A.T.C, 1119D, 4542340" (comma indicates linebreak).
