I think I found where the problem is.. I took the A190 off and inspected. A close look revealed that the microcontroller (S-80C32) has a very small and thin crack going from one side to the middle of the processor. Very Good.;-) I think this is quite a common component, am I right? But where can I find one (last night I started looking for old motherboards, opening Commodores 64, ZX Spectrums, Gameboys.but nothing ;-)))) I've checked rs-components but they have so many different variations of the same components and that drives me mad. I'm pretty sure I have a old piece of electronic junk lying around that uses these processors, but what exactly? A. [Non-text portions of this message have been removed]
