Is my 1200 dead?

yes, it is.
you could modify your sig..  :egad:

now seriously, have you checked the voltages? esp +5V on chips. AFAIK, besides CPU, Alice should get hot too

well if you're not skilled forget checking voltages, its too easy to short something.

BTW you can find custom chipset pinouts very easily, probably on aminet just search a little.
once you have the pinout, you should connect the red wire to "+5V" or Vcc pin and the black wire to GND. its a bit hard to count all those pins and also set the (digital?) multimeter to something like 20V DC

surprisingly, Alice is the chip labeled as .. "Alice"  ;-)
its left to CPU, skipping the missing one.

why don't you check power supply voltages with multimer, it should be relatively easy.

HDD can be checked in PC esp. laptops.

to be safe: have you waited long enough after disconnecting HDD for bootup?

I'd say the accelerator has good chances.

which cables did you move?
