I am aware of the real hardware problem, if that is the one that tended to show up with multiple devices off the bus. I read somewhere that the PAL replacement was one fix, while adding a connection internally between two points was another fix. When I installed my Insider, the docs suggested that as long as I had the cover off, I might as well add the connection; even if my system didn't suffer the marginal problem, the extra ground wouldn't hurt. The connection was from F02, pin 7, to the left side of resistor C31 (near DPALEN). Michigan Software did not say that this fix was as good as a PAL replacement, but I did read something like that elsewhere. So, if it is just as good, I've got it done, and shouldn't have to replace the PAL; if it's just auxiliary, I will have to replace the PAL. Anyone else remember anything like this? /Mike
