Hi, some years ago I asked this question on a forum (maybe not this one?), and may have gotten an answer, but I don't remember.
What is this 4-slot hex backplane?
Markings: "6101269-1 Rev. G S/N 17079"
The metal frame is marked "03239G1".
You can see that it is hand wire-wrapped.
On each row, pins A2, C2, and T1 are bussed together. Seems like Unibus power.

It will be listed on eBay, so I'm wanting to give an accurate description.

Thanks,
Pete
