[net.unix] Query - Host-IMP Interface for SUN?

dca-pgs@DDN1.ARPA (03/07/85)

Does anyone know if there is such a thing as 
an LH/DH 1822 Host-IMP interface for the Sun, whereby
a Sun WS could interface directly to an IMP?
I have a co-worker who asks me about this,
and don't know what to tell him.

Thanks,

There is an 1822 board for the Sun.  Glenn Hastie (hastie@sri-spam)
wrote a driver for it. ACC makes the board.  I believe that the
no one has actually tested the board hooking it up to an IMP,
it has been tested with Packet Radio, though.

PS it should work just fine -- the sun has all of the berkeley IMP
software in it.

Uh... I dont think so.  You really don't want to do this.  If money
is an object, build a fuzzball or something as a gateway machine
that plugs into the IMP and have it output packets on the ethernet.

That way you don't have to kludge up the sun and it'll offload the
gateway functions onto the fuzzware...

Actually, I think it would be much cheaper to buy the 1822 board
for a Sun (I assume they already have one and are asking if
they can connect it up to the arpanet) than to buy the hardware
for a fuzzball, or a normal gateway... unless they already have the
right hardware laying around.
