Good luck with your new machine!

...or you can just post here. There are lots of DECheads here. The
pdp11 field guide covers many boards which can be used in both PDP11
and VAX systems.

Well, ordinarily that would be an issue. But these machines don't
Seriously. They just *do not break*.
This reminds me of a story. About 12 years ago I was working at a
gov't contractor facility in Princeton, NJ during severe weather. The
building was hit by lightning...squarely on a power switching box for
an air conditioning unit. The damage:
- about 30 PCs completely destroyed (some of which produced smoke)
- six laser printers destroyed
- two Emulex Performance4000 terminal servers smoked
- about a hundred PC and terminal keyboards destroyed
- two SGI 4D/20 workstation power supplies destroyed
- Nortel phone switch smoked
- nearly every color monitor in the building needed to be "deeply"
...this amounted to pretty much everything that was plugged into a
power outlet in the building.
Except, of course, two MicroVAX 3600s (KA650, RA82). One indicated a
spurious interrupt (or something along those lines) in the error log,
and the other didn't notice at all. They didn't even reboot.
