I have a sd2iec which worked flawlessy until i booted it up one day. Only thing i get is "device not present error." I have tried 8,9,10,11.
When i turn on the device, the red light gets lit, and then the green and both go off. Just like "normally".
It does respond to the disk-swap-switch; i press it for a few seconds and the red light gets lit and stays on. Press again for a few seconds and the red light goes off.
I tried to insert a newer firmware onto the sd-card just to see if it was alive at all, and yes, it did the upgrade cycle (watched the leds).
If i have another drive(15x1) as same device number the computer hangs when i run an "@IO", so its there but still not.
If i have 15x1 as #8 and sd2iec as #9, then the "@IO" works on dev#8, but dev#9 gives "device not present".
I have measured all cables from the sd2iec PCB to the c64. All ok.
I have an identical sd2iec where the SD-card works.
Not sure what to try next, any suggestions/help appreciated.
