It wasn't NE-2000 compatible > (that came later) :). LANCE seems plausible, or perhaps one of the later chips designed by DEC Jerusalem (SGEC etc.). What's a SONIC? The non-LANCE non-DEC Ethernets I remember are in the DEUNA (no idea what), QNA (Fujitsu???) and CNA (Intel 82586, *groan*). The LANCE was designed well, with a fair amount of DEC input, and the subsequent internally produced chips were constructed along similar lines. Once DEC learned how to make them at not quite insane cost, they became a very good choice and were generally used in DEC products. paul
