So, just like the Schrödinger's cat, it will be the Schrödinger's A1000.
Is there an A1000 inside the box or not? No one will ever know and the A1000 could be in different points of the space-time continuum at equal probabilities: that's quatum physics 
At least, i take for sure that there was an A1000 inside the box just one second after the box was closed at the Commodore factory on 1985 
Yup. There is and there isn't an A1000 in the box. So long as the box never opens it is still in the Commodore factory, brand-spanking new and fresh off the assembly line. Once the box is open, however, it will be yanked into the future, dry electrolytic capacitors and all.
This was Commodore's genius: Quantum Product Distribution. The assembly lines are chugging away in the 80s and early 90s producing Amigas for us to open today and into the future. Just like those CD-32s that "turned up" several years back. This, IMHO, was Petro's big failure with his 1200 Magic Packs, that he had the 1200s delivered too soon from the 90s by opening the boxes to sign them. If only he had been privy to Commodore's QPD system.
