hey all.. got my core working.. tested it with the interconnection test.. everything checks out.. all voltages are good. .even the 12v line looks good.. but when i put the chip in, the crystal and sid, get hot! any ideas?
Hi,
most SIDs are getting very hot, some not. Hey, thats analog gear 
I don’t see problems so long the voltage at pin 28 is still 12V after power-on. If it’s much lower (< 11V…), a soldering error could be the reason. But if you see >11V, then you’ve got one of the older chips which consume a lot of power.
