So, here are a few photographs of some original Ethernet (10base5) bits
I have here --   Etherpipe, AUI cables, and h4000s and h4005s.   I put the
camera away before I'd realized that I'd not photographed the tap tool.
I hope you won't be too disappointed in that.

Nice.   Interesting to see the yellow stuff, I remember that in prototype installations but from what I was told, DEC switched to the brownish/orange teflon jacketed cable for customer shipments.   Something to do with flame rating for air handling spaces (i.e., dropped ceiling office areas).

I think we still have some yellow coax under the floor, still with transcievers attached, in the hall where Magica and Mim are located. However, the coax is cut somewhere, so it is no longer usable, and I don't think we have DEC transcievers, but I can't remember what we have. Maybe someone could check and take a photo.
All of that was installed along with our two DEC-2060s back in the 80s...

And it's definitely bright yellow.
