    coincidentally i was playing around with this in VICE at the weekend, so here is all you need:

    First time someone reports such a problem i think - being a popular product, we'd know by now if there'd be a problem with the micromys and Amiga. *shrug* What kind of power supply are you using? Do you have a multimeter so you can measure the 5V at the joystick port?

    To be crystal clear, I have a C64c with one socketed 6526A 4989 2161A on a rev A PCB, I can swap it with the CIA socketed on the Reloaded PCB next to the Joystick port correct?

    Yes, all CIAs are interchangeable (6526A/B/C and 8521)

    On social media, I read that the two CIA'S can be swapped is the correct?

    like i said, swap them against each other - if one of them is broken then the problem will change (you might get a cursor, but now the disk drive wont work. or something similar. CIA1 is the one responsible for keyboard and the timer interrupt that makes the cursor blink)

    the SID chip locks by pulling upwards, is this normal?

    That sounds strange - all sockets are the same kind, lever down is "closed". In any case, while testing take out the SID, you dont really need it (except for sound of course)


    Now, a simple test is to swap the CIAs against each other. If that somehow changes the behaviour, you know one of them is bad

    1. never use contact cleaner

    2. isopropyl is fine, however you still need to wipe over the respective contacts, which will be kindof hard inside the sockets


    that means wiggling the ICs sideways is really the best solution. open the lever of the socket "halfway" in case they dont move easily.

    I think track is the minimum if you want to reproduce stepping offsets etc properly without overcomplicating it... and indeed, the stepping time should be enough to read it from sd card.

    working on a bitstream rather than flux should indeed be good enough for most things - most of the time you will have simple things like "a sector exists twice" or so anyway.
