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.
