    It's honestly a motherboard that will drive you bonkers. I've had 2 problems with System 32 boards. One being that IC16 sound problem and another being a weird graphic glitch that pops up randomly. The first guess was obviously a loose solder joint, but neither Ken (at Irepairsega) or I could find it and it drove us bonkers. We also tried looking to see it was a bad ram that was randomly glitching to no avail.





    In with the real hardware, out with the bootlegs......who is this I wonder?

    Don't piss off cats or you'll get the Nyanyan Uppercut!

    Should Z80s A0 line connect to any of those 74244s like other address lines? I have soldered socket for the z80 and can't quite see the traces. I managed to get rid of most of the ringing in the clock line and found two legs I had to reflow in one of the sega chips but still dat ic 16 bad and no sound.
    If the freedom of speech is taken away then dumb and silent we may be led, like sheep to the slaughter.

    I hate to revive a 17 month old thread but I am having a similar issue with a Rad Mobile, did anyone figure out why this system's sound dies out?
