The floppy drive is touching the socket for the rom but I have taped that and will bin the floppy for a gotek eventually. Could it be the ce wire?

And as I said, sw has nothing connected to it.
odd.. check pin 1 of the GAL make sure you have 40MHz there... I did test the boosters before I sent them out, so no idea why its stuck in 8MHz mode unless the osc has died. :shrug:

Nothing at pin 1 of the gal but an 8mhz signal at pin 2.

As far as I can tell there us 5v going to the osc but not a lot coming out.

Can you check the contacts on the osc itself and make sure it has 5V on top 2 pins, gnd on bottom left, and 40MHz bottom right... either its a bad solder joint or the osc has died..

Actually checked that after I posted earlier, so looks like the osc has died.

Damn, What is the number on it ? There was some 3.3V ones which seemed to work fine on 5V.. though I got the 5V ones for the production runs just to be safe..

Thanks, no rush at all.

Just wondering about the best way to remove the faulty one, presuming the heat could have an effect on the cpu soldering?

What do you think?

If you put a bit of flux around it, I use a small gas soldering iron and just circle around it and it comes off easily... If something you can't easily do then just send it back..
