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
