Hello Everyone, First of all, many thanks to Thorsten, SmashTv and this community for so many great projects and information. I have been lurking around here for a little bit, mostly trying to get educated as I'm pretty new at this stuff. But, I have almost completed my first midibox sid from parts I purchased from SmashTv. I am having an issue however where things reboot after about five minutes of being powered up. ??? I'm currently running MIOS version 1.9f on PIC18F4685 with a 6581 SID. At first I thought the problem might be power related, but I checked the power supply on an oscilloscope and even during the reboot, the power was constant. In order to try and narrow the problem down I reinstalled MIOS. I ran that for a while and no rebooting ever happened. As soon as I install version 2 of the SID software however, then the reboots start to happen again. Has anyone else had this issue? I've tried two SID chips (6581) and both exhibit the same problem. Could both chips be bad? Many thanks in advance for the help.
