It seems a bit odd that a power supply from someone like DEC of that era would
be designed to depend so critically on the absolute value of a rail used
for startup purposes.
The output of the replacement 7812 varying between 12.2V and 12.4V suggest that
the 7812 itself could be faulty. Or maybe
Out of stock in the manufacturer, I am on the waiting list for one, it is
used on my crystal ball.

I read the request at the ns32k site and I found out via another
request, that the datasheet has been published in the Elektor Book
"IC-Datenbuch teil 3". Perhaps you find an owner of that book.

Ok thanks guys. Here is a better picture of the inside cover

I would love to find a manual to this. There are lots of extra bits stored
inside a compartment. But I am not near the unit at this time.
Anyone have any idea about where to

Creality's slicer software is a fork of Cura.
Cura can rotate objects on the platform during the slicing process. Not
sure I've ever actually used Creality's version, but in the more generic

Thanks Dennis and Gene. That did the trick.
I tried to do that but it seemed all I changed was view but with your
suggestions I found the right button and am printing one of the odd
pieces right now.
Finally I can have enclosures for all these boards I run just sitting on
top of

Further to Peter's point above, the 1988 NatSemi databook
With all due respect, Bill, this is a 3D printing mailing list question.

And what happens if you feed in exactly 12 V on the output of the 781
