Uh-oh. Trying to be too clever for my own good...
Well, I thought I'd be clever and desolder the DIL-14 crystal on my accelerator and replace it with a nice socket instead. It all went well; the crystal came off pretty easily, the socket on and soldered neatly (for my standards, anyway), no solder bridges that I can see, no burnt traces.

Then it all went pair shaped....
It doesn't work any more :o
Original 40MHz crystal, or either of my two new 50 and 56MHz ones. Nothing. The system won't boot with the accelerator installed.
I don't know what I've done; I've done much smaller repairs than this before, and I'm sure I haven't damaged anything.... but he's dead Jim. :(
I guess I'll have to try taking the socket back off again.... oh what fun....

Socket is off again.... and .... I can't see what the problem is!

Everything looks clean :nuts: Only thing I can do is try again. :dry:
