Amiga Anitclimax

In the throws of the sort out, Martin came across his old Amiga 500 Commodore, and has been trying to get it to work.

He had it when we first met when I was obsessed with playing 'Bonecrusher' and 'Lemmings' on it.  We found a 30 year old handwritten list of passwords for each of the levels with the floppy discs...

...Which we still have  (remember them?) and would love any  advice or help with getting it up and running again.
