A dead SID chip does not equal a dead machine (it's still useful for lots
of software, even some games like Zork). The thing that I've see die
(besides the occasional DRAM) is the 82S100 PLA. It runs hot and it's at
the hub of the machine. When it dies, you get a black screen.
I got a dead SX64 once for $20 - bad PLA. It took longer to crack the case
than to diagnose the problem. What also dies on _those_ is the keyboard
(low-quality membrane). I haven't done it yet, but I'm tempted to turn a
C-64 case and KB into an external KB for an SX64, so I have a spare.
