One concern that I had was that the new design might end up trying to
ovalize the (brittle) socket in the mating panel, since the new posts
are only really compressible in one axis.
I doubt that matters much either, because it's the posts
If you were following Joerg Hoppe's recent PC05 auction on eBay, you might have

as it should.

It's basically SpaceClaim that's been tweaked to only output it's native

Hello Folks,
I just assembled an Ultra-10 (replaced memory, CPU, NVRAM chip, IDE hard disk,

Can you estimate weight on the SHD1Z-ZZ? That's all DEC RZ26 drives in

DEC made improved cards in many cases, where they added a 0 at the end
of the improved card.
The other thing one will sometimes find (in PDP-11's at least, not sure about
other machines) is that an M7xyz is replaced by the upgraded M8xyz, e.g.
M7265, M7266
A lot of the early unibus boards which were 3 digit and replaced by a 4
digit were duel height boards that required a M7821 and M105 (not sure
about the numbers), and DEC built those into a quad height board and added
a 0.
