OK, maybe not, maybe the power supply is toast. It reads 12.6VDC, little to no ripple at no load and when programming the PS reads 11.3VDC with 0.17VAC ripple, when the package says 9VDC. I didn't find anything about PS caps, the piclist site has a page about "wallwarts" and a non-wallwart power supply, and it says that it really needs 9VDC to work, much more won't work properly. I have a wallwart and the thing is sealed, I don't see a way to replace caps without breaking the case. Suggestions? I tried the archives but nothing relevant seems to come up with any permutation of these key words: picstart plus capacitor replacement power supply problem Jeff ----- Original Message ----- From: Jeff DeMaagd > > I have found a third 'F877 that programs and verifies just fine. > > ----- Original Message ----- > From: M.
