Sound & Floppy issues on A1200

r6stu · 05 November 2005, 12:46

My A1200 as lost all sound and I am unable to load from floppy.

If I stick a disc in the floppy drive the light comes on and dfo:???? comes on WB and thats it. If I take the disc out the light stays on!

It was working one day and not the next.

I do have a spare 1200 mobo if needed, however the PCMCIA slot as a few broken pins.

Is it an easy task to unsolder the PCMCIA slot and stick a new one in?

My A1200 is my pride an joy and is in new condition!!

Try another power supply.. Missing sound would lead me to believe you aren't getting -12V from the PSU.

The Paula chip controls both the floppy and sound output. Maybe it's knackered.

Sorted it!

It seems to be the power supply!

It is one of the goliath PSU's. Is it simple enough to take it apart and stick a new PC supply in there??

Or what could be going on for that to happen?

Those goliath supplys are standard AT 200watt! Maybe its going to kick the bucket?

All you need is another good AT supply and swap them over, if you take the lid off the goliath you will find all they have done is fit an off the shelf AT supply, then soldered a custom connector to the amiga power lead and fitted a funky led power switch
