So I found an RXV21 board in the pile of stuff here

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.
