My old faithful Wallstreet II (266mhz) has been languishing with a failing hard drive and a failing display (a rectangle of artifacts covering about 1/3 of the screen), so it being the Christmas holidays and me having some time on my hands, I decided today to do some work on the machine today.
I have replaced the 40GB drive with a 30GB that I had on hand, and am currently imaging the old hard drive for installation on the new (transplanted it into a Pismo, booted in FireWire Target mode, and am doing the imaging on a G4). I hope it continues to spin long enough to recover all my old files, but nearly there, so here's hoping.
The graphics problem is a bit more involved. The initial assumption was that the trouble would most likely lie in the data cable (the earlier Wallstreets were notorious for it) , but as I had a parts Wallstreet body here, I started out by transplanting the problematic screen to it, before I started disassembling things more thoroughly, only to discover that the screen and therefore the date cables are just fine. Works perfectly, and as the parts main body is in good shape, problem solved.
There is still, however, the question of the failed machine, where the trouble must lie on the logic board.
So here's my question: is it more or less given in these circumstances that the graphics chip is fried, or is there a simpler solution possible, namely, that there are capacitors to be serviced on the machine? Can failing capacitors cause graphics artifacts? Anyone know?
