im messing around with a broken iic (us version) which i got here in germany...
It wont post / shows marbled graphics. It tries to read from my floppy emu but ends with errors...
i managed to check system with rom4x
(most of the time the machine gets stuck while testing maybe in 1/100 i got different Ram Errors...)
is this because of faulty ram? i am able to swap these but im not an pro with osci and so on... is there a chance to fix this or might there be more involved like broken IWM ?
