[RE-wrenches] Old and new Radian

[Michael Morningstar]

I just pulled out an 8048 and replaced it with a 8048A due to the lack of
AC boards for 8048s. I didn't know any better and put in a new 8048A board
and learned the hard way that they aren't cross compatible. Smoked it. If
you think you can find a board for it, it's yours.
