Is it possible to get DECnet Phase IV and/or TCP/IP running on the SIMH
simulation of TOPS-20?

I realise that the SIMH PDP10 does not simulate the necessary communications
hardware, but if I can find suitable documentation I could write that
myself.

However, I have a feeling that the minimum version of TOPS-20 required is
too high and so may need the KL which I know SIMH does not simulate.

Thanks

Rob

Phase IV DECnet worked on the KS for TOPS-10. Now I can't recall if
it was certified for TOPS-20 on the KS.

If you want to look at ethernet connection code for the KS, the
code was shipped with TOPS-10 7.03.

Hmmmm. What ethernet hardware did people use on the KS? DEUNA? Anything else
supported? IIRC TCP/IP was never supported?

DEUNA/DELUA is the only ones DEC had, so I would expect it to be them.
They are compatible enough that you use the same code to handle both.
(Different microcode in them, though. The DEUNA is T11-based, while the
DELUA is MC68K based.)

The Panda distribution, which includes SIMH, does TCP/IP. I didn't try
if it does DECnet, since I don't really have anything to test it with.

It is based on klh10, not simh.
