I am not sure what the actual distinction is, but a 'managed bridge' turned up at the local antique market (!) some weeks back. It has a pair of AUI ports and from the amount of logic/processor power inside it does a lot more than just pass packets from one port to the other, The main board contains a pair of ethernet interfaces (AM7990 based), a 68020 processor, ROM, RAM, etc. A board on top of of it called the 'FLUT' (Frame Look Up Table?) contains a CY7C901 (16 bit slice ALU -- think of it as 4 off 2901 + carry loglc), a 29C10 seqencer, etc After removing the leaking NiCd from the mainboard and repairing the corroded tracks it powers up and passes the self-tests. No idea what I'll use it for, but... -tony
