[R-390] Z503 Replacement - Apology

[rbethman]

I have screwed the pooch on Z-503.

I kept mixing it up with *T-503*, a completely different animal.

Things around here have been hectic due to family issues.  I'll let it 
suffice to say that it has been chaotic to double the population of your 
house, with *little* warning.  I can't even find my hard copy of the 
manual now.  I'm trying by opening up a PDF as I grope through the 
operation and circuits

I won't go there, but it is what it is.  Sorry I got wrapped around the 
axle!
