Not quite Amiga, but in my shed, I've had a boxed Atari ST/Falcon RTC with disc. it still has some packing nuggets and the cover as well.

I could not for the life of me find out anything online worthwhile, other than the computing museum in Cambridge have one.

So I contacted Ravi at the retro hour and he spoke to his dealer mate. He told me this was mega rare and could fetch up to £2k online, with a low price of around £1200.

Being a dealer his mate has offered me £700 for this item.

Umm, this would pay for my bike to be fixed nicely!
