Ok, after some testing, the keyboard membrane is damaged and thats why the keyboard doesnt work properly, its actaually black along quite a lot of traces under the spacebar and other keys, so I've got a replacement membrane on the way.
Floppy drive does have problems even though its reading, I'll open it up and try to clean it.
God knows whats going on with the mouse, I've tried another on this Amiga and it seems to be happy with it, maybe the original mouse I tried is faulty.
I also thought I had a graphics fault on the machine, when running the State Of The Art demo on WB Classic I was getting graphic corruption, but it's the same on the other Amiga with the same CF card, so it must be either CF card or maybe I've set the Max Transfer wrong, or possibly a bad install of the operataing system.
Think I've jumped to conclusions to soon when I got the Amiga and its not as bad as it seems.
Hopefully I'll get it all sorted.
