G"day All
My Apollo 1240 accelerator seems to have died.
This is what I've found so far:
When i power my A1200 all i get is a black screen. i can't even get the early boot screen by holding the two mouse buttons on boot.
The fan om the 68040 works when i power up.
I've put the RAM Simm in my A4000 and its ok.
Put in a different SIMM in the accelerator makes no difference.
Take the accelerator out and the A1200 boots.
Put the accelerator in another working A1200 and get same black screen, not even internal floppy clicks.
The clock crystal is not soldered on the board. I have another old crystal untested but putting this in makes no difference. In fact its the same black screen even if have no crystal there.
Normally the 68040 and crystal get warm, but not since the black screen.
I had this problem once before and it was because the crystal was dislodged, simply pushing in its socket fixed the problem, but not now.
Has anyone else had this problem? Would it make a difference soldering a new crystal onto the board?
I'd appreciate any suggestions.
