  Did you mean DECnet support in IOS, or DECnet itself?   DECnet itself
dates to the mid-1970s.

What I haven't found out is when the IP tunnels were introduced in the
IOS. It seems to be in IOS 11.2. So it is included in all recent
versions, but the Cisco 2500's have limited flash and RAM capabilites.
Therefore the recent IOS's cannot be used with older hardware. I suppose
the IOS 11.2 should be sufficient for tunneling DECnet over IP.

  I'll bet much older releases than that would support this.

I have to check which versions I have on my 2500's. Most probably they
have an IP-only version of the IOS. I bought the 2500's cheap from a
local broker a few years ago.

  I've got lots of IOS images if needed.   Let me know if I can help.
