Have you seen this part of the video where David Boggs
(designer of the
first 3 Mb Ethernet card for the Alto), and Ron Crane (designer of the
10 Mb Ethernet) are doing a show and tell in their own words? You get
to see the clamps, the drill, the transceivers, the cards, and some of
the inventors. Regrettably Ron passed away a few month after we took
the video. We still miss him. https://youtu.be/XhIohWr10kU?t=4m27s
I really liked that video, and the entire Alto restoration series from
CuriousMarc.
I've got to say, I think David Boggs saying "?very simple off the shelf
stuff, for people who want to know, it's RG-8. ? This is the 50 ?
version of it." I can fairly clearly see the RG-8/U on the side of the
cable that David is holding at 8:01. That's good enough for me.
Sure, there was probably a better alternative that came along after,
with better shielding and marking bands. But it sounds like RG-8/U is
definitive acceptable to me. I'll assume that David meant quality RG-8.
What I don't know is if RG-8/U was used for 3 Mbps and then something
else was used for 10 Mbps.
