So I found an RXV21 board in the pile of stuff here and popped it into
my 83. Crashes the system. It's an M8029 D board, and I see from this
site that you have to add a few traces and cut a few others to make it
work on an 11/73 or better.

I'll pop in an 11/23+ CPU just to test it, but is it really just
putting in two wires on the top of the board and cutting a total of
three traces? Looks simple enough...

My M8029 stamped Rev F has three jumpers and three trace cuts. It
matches the images posted in the link and works with an 11/73 ot 11/83.
But yes, it should be that simple.
There is a sharpied H on my card, which it is not the way DEC marked
these boards. The available field maintenance prints refer to this (no
G). I don't know what the change was.
