[Coco] 512K upgrade for CoCo 3 on eBay

There was one brand of upgrade board that did not shorten one pin key 
that would reach though the connector and short out a line to the CPU, 
instantly letting the magic smoke out.
That said, this since this one was used is probably not one of them.
As soon as I can find it in the midden heap, I plan on shortening that 
pin and will offer it for sale.
It took a lot of searching to find out what killed my 68B09E, but the 
"good" part is that I socketed the replacement 63B09E.
