The characters doesn't changed. They also doesn't changed if i push the reset button.
I get only a changed screen if i power off/on.
Get no beep.
The chips are relative cold. Except the 6809 Chip. It gets hot. I can touch the chip. But its getting to be uncomfortable

Hmm... that might be a bad sign.
I suppose if you have another ROM sitting around then you could try it. But if it was me, I'd really want to verify that the CPU is actually ok before spending much time replacing other chips.
I buy a CPU from Tormod. Should be arrived next Week.

Oh wow, USB oscilloscopes with OpenSource Software! Great!
But i can't find a list of supported devices by OpenHantek.

200kHz is really low. I dunno, I'm not sure it would help you much with the parts that are most likely to fail.
Also only having one channel might prove slightly annoying - being able to clock off one signal (e.g., FS or HS) and watch another is often really useful.
All IMHO of course. If it were being offered up for a pint I'd still go for it
Then i will look for a old-school oscilloscopes on ebay.
