I'm sure other people can do better, but I offer this:

  Cisco Internetwork Operating System Software 
  IOS (tm) 3000 Software (IGS-D-L), Version 11.0(16), RELEASE SOFTWARE (fc1)
  Copyright (c) 1986-1997 by cisco Systems, Inc.

  [snip]

  cisco 2500 (68030) processor (revision A) with 16384K/2048K bytes of memory.

And this:

  Cisco Internetwork Operating System Software 
  IOS (tm) GS Software (GS3-K-M), Version 10.3(3), RELEASE SOFTWARE (fc4)

  ROM: System Bootstrap, Version 5.3(2.6), SOFTWARE

  [snip]

  CSC4 (68040) processor with 16384K bytes of memory.
  X.25 software, Version 2.0, NET2, BFE and GOSIP compliant.
  Bridging software.
  1 MCI controller (2 Ethernet, 2 Serial).
  2 Ethernet/IEEE 802.3 interfaces.
  2 Serial network interfaces.
  32K bytes of non-volatile configuration memory.

That's a CGS we bought in 1989 though the original CSC/3 was replaced
with a CSC/4 taken out of a retired AGS+.
