It seems ok now. I did remove the shielding just in case. I think I have some more from when I towered my main A1200, so I may replace it with that.
In order to remove it I had to take the floppy drive out, and I found something very interesting. Underneath the drive on the shielding was loads of black insulating tape. I turned the drive over and there was an exposed PCB - not something I have had on any of my other Amigas, and obviously the reason for the insulating tape.
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.
Could it be that the drive has been changed to a non-Amiga one? This would clearly mean that it has "bin" opened after all!
After removing the shielding, I inspected the motherboard. First thing I noticed was that the rust has extended to the shielding on the RF modulator. I then saw a sticker on the motherboard for "Macklin Repair" stating "RF not working". No sh!t.
I'm now convinced that the machine has been opened. The warranty sticker was still there, but was a little bit damaged on one edge. I reckon he took it off then replaced it :pissed:
