[Racal] More RA6790 woes

[Robert Nickels]

The good news is - I no longer get BITE faults on the A8 module.   The 
bad news is, I get one on the A7 module now, and all signs point to the 
N82S83 BCD Adder, which of course is No Longer Available.

So I thought I'd ask if anyone might have one - or know of a source.    
Also, I've mislaid Gary Wingerd's email address, as I would like to 
check with him.

Thanks and 73,

Bob W9RAN
