I missed the recent M8198+CIS chip auction on eBay, and subsequently
found myself with a new (for me) 11/23+. Does anyone have a CIS chip
they're interested in parting with? Contact me directly.

A couple of boards from an unknown computer came in and i am trying to get
them to a good home and not be scrapped. I was curious if anyone here knew
what they were out of. They were in the box with some small core memory
boards. If someone here wants to make an offer ill gladly take the ebay
listing down.

No, the original 3 Mbit Ethernet also used a 'drill' (actually, a cylindrical
cutter which screwed into the thread of the tap housing; threading which was
then used to screw in the transceiver).
Anyway, there has to be a hole cut _through_ the cylindrical ground layer
(foil, or woven wire) around the center conductor. If you just stuck a probe
into the cable to the center conductor, it would short it out.

If your system works properly, the grant cards are in the right way. If the
grant cards are installed wrong, or missing, it will cause serious
problems, and you're unlikely to be able to boot anything.
I don?t recall if I had any 3880 documents. I will ask how they would like to handle this type of request. There are many duplicates and they will need time to catalog the documents.
