Help compile giant list of Amiga hardware vapor

[Zac67]

The A3000+ was an A3000 with AGA chipset plus DSP, the AA3000 was a supposedly cheaper design (IDE instead of SCSI, no DSP, no onboard CPU) and finally became the A4000 - I would not regard those two as vapour since they were prototypes/developer machines.

What's definitely missing: when it became aparent that AGA would surface, C= announced a Z III AGA upgrade card for the A3000/T to save those machines from starving on the shelves - obvious vapour!

Many products have never been announced and therefore cannot be vapor. Additionally, it does make a difference whether a product is announced as a future product or a mere design study (e.g. Boxer).
