Hi Peter.. when is this the IGS's that have a 16Mhz m68020 in them? I think I've got one or two (Although I've not dug that deep in over a decade). At startup, it says: Cisco Internetwork Operating System Software IOS (tm) 3000 Software (IGS-BPRX), Version 10.0(6), RELEASE SOFTWARE (fc1) Copyright (c) 1986-1994 by cisco Systems, Inc. Compiled Tue 25-Oct-94 19:01 by dougs cisco IGS (68020) processor (revision A) with 4092K/512K bytes of memory. I can't find any reference to the processor speed anywhere. Regards, Peter Coghlan.
