Hallo Philip,

Yes, but...

It shouldn't be caused by my program, AFAIK. That's why I gave the
source as well so you or anyone can check. 
But have a better look:
- not 256 characters are shown but 260.
- column 2,3 and four are a copy of the last three columns (= 3 extra)
- column 1 is a copy of column 2 (or the other way around) (= 1 extra)

My question: did you replace the CPU already? Unless someone comes with
a good explanation, I suspect at least the CPU. And it just takes
seconds to replace and check it.
