So, what needs to be preserved? How much of this does CHM need to do? Is any other
collecting institution already covering this? How much is within scope?
Al, you are probably very far ahead of me, but I have two suggestions:
1) ?bridge? pieces - the Kindergarten example is probably a Dayna EtherPrint-T or Asante
EN/SC type device that allowed a LocalTalk network to bridge to an Ethertalk network. In
terms of long-term, serious restoration/preservation, having one of those available means
having a device that could be (maybe) deconstructed to give information about both types
of network. It also seems pretty helpful to anyone trying to restore hardware on the
less-used (LocalTalk) side.
2) Interconnects used to parallelize processors in supercomputer families - Infiniband and
the like. This may be a hard goal, but it could be that retiring supercomputer sites may
have the stuff available, and recalling the Cray software discussion going on now, this
might be a good time to ask. And, looking far ahead, some characteristics of these
interconnects will be needed to supply the voracious data demands being put on the
internet, so they may serve as prototypes for data center interconnects in widespread use
years from now.
My two cents, HTH.

Agreed, though I should point out that the EN/SC was actually
a SCSI-to-Ethernet converter for SCSI Macs that lacked expansion
slots (e.g. Plus, Classic, not the SE, though I used an EN/SC on
an SE when SE Ethernet cards cost their weight in gold).
LocalTalk itself is pretty well documented, at least. The book
Inside AppleTalk is a pretty great reference for all modes of
AppleTalk, both LocalTalk and otherwise. A lot of the bridges
are pretty dumb, requiring the LocalTalk side and all its
devices to be alive at boot time. I'm of a mind to make my
own that's smarter, but I need to stop pushing more projects on
my stack.

I have several boxes of Myrinet stuff
available. Switches, cabels
(copper and optic), PCI cards. The stuff is around 10 to 15 years old,
speed is 1 or 2 GBit/s. (?) I never intended to use that stuff. I just
saved it from the dumpster because of its historical significance. So:
Free to anyone who takes it out of my hands in Kaiserslautern, Germany.
