My CPC6128 is alive again!
Igor, bring me the video camera and don’t forget the Aspirin for my head!
@Bryce I´m using a switching power supply for the CPC6128 and also for the ext. floppy.
5V with max.5A and 12V with max.300mA.
I had a very nice and helpful email conversation with [centpourcent] and the result was:
CLEANING! Every socket, Z80, GA etc. and also the centronics plugs on the back and [important!] the power switch beside the volume wheel. I used WD-40 contact spay and a hard hair brush.
And now everything work perfect! Also the ext. floppy. (There was no failure in the ext. floppy wiring.)
In addition I use the “old” chips again, so no one was burned, just bad contacts.
Thanks to all helpers and this great forum!
