@Dr Bongo. I got the 2 Amigas. Bad news Is neither worked properly. Good news Is Out of all the brokens. I managed to get a fully working Amiga 500. Here's how I achieved the feat
My old Amiga as you know had No sound but a prefect floppy drive
First Amiga I got today kept blinking black and green but a Dead Floppy drive
Second Amiga I got today Had a nothing wrong with It but a faulty floppy. It wouldn't read the disks and kept getting error messages.
I moved the perfect floppy drive to the good Amiga with the Faulty floppy and took the clean case from the Amiga which had the green and black error.
I now have a fully functioning Amiga, pending test as I think the keyboard Is non responsive with a few key. Not a problem though. I will use either keyboard from the now Spares department I have created lol
