The A1200 that has never "bin" opened...

[BadBigBen]

1.) Mine does not CLICK, though I have a Programm running to not do that... he he he...

2.) I took a look at the PIC, and I never seen a A1200 that only the keys turned YELLOW and the CASE pearly white... LOL...

3.) BTW what does the DRIVE say as to type and who made it...?

If the rust is not too thick you can remove it using chrome polish. The bumpers of my beetle look like this from time to time and after a good rub with chrome polish they look like new. Only the badly rusted parts leave black spots. But if you feel better with a shiny sheeld go get some chrome polish from your local car shop.

I have had floppy drived from Mitsumi which has all its installs showing on the underside.  Chinon probably made the most armoured drives and lots of jumpers on back to play with too.  Panasonic drives used in later a1200 are practicaly silent so it may be clicking, just not audiable.  Would have thaught floppy led would have a very slight flicker to it.  If it is a mitsumi drive its internals could be grounding on the shielding which would stop drive functioning properly.

Well ive had a few amigas and i think they all clicked from the drive but yeah there is a program to stop that..
Maybe there is a few out there that dont click then???Who knows but glad its working now..

I had noticed that the drive was acting strangely. Firstly, it doesn't click when empty. Secondly, if I boot using a Workbench disk then remove the disk, the drive starts clicking like mad, the floppy light comes on and a DF0:NDOS icon appears on the Workbench. If I put another disk in, it reads it and this weird activity stops.

Seems like it thinks that the disk/floppy is still inserted even when the drive is empty. There is a button or what you call it that is pressed down when a floppy is inserted.
See if this button is stuck or something.

Or as you said, the drive might infact be a pc/mac floppy without this function.

How did that shielding rust like that, I thought they were aluminium? If it's tin then it must have been left in the garden shed over winter!

:-)

If there's oxidation taking place then everything that isn't surface mounted is going to have transmission trouble - the same happened with the internal power connector in the Sega Dreamcast.

The solution to the Dreamcast problem was to moisten a lint-free cloth with WD40 and rub gently over the connectors. WD40 is excellent for removing specs of rust from chrome (try it Doppie!) and can also lubricate and improve contact.

So maybe try cleaning the ROM legs, floppy header etc. with fibreglass pencils from Maplins and give it a little WD40, same for the shielding (although best clean that after removing it far from the motherboard).

Every Amiga is precious and that motherboard could serve you like a work-horse for many years!

Rusty Amiga I salute you!
