Ok crisis over, new bedroom ceiling in as it collapsed and all new insulation as it was sodden....got to get the plasterer in now grr.
Sorry to say the amigas had to take a back seat whilst this was going on but now are laid out drying in the front room much to the mrs's dismay lol.
Casulties are 2 boxed a500's, my 2 1200's including my prized 1240 accelerator , several boxes of disks,1 cardboard box with big box games in, acorn archemedes a3000 not to fussed as it didnt work correctly.
My A600 didnt get wet as i first thought so lucky there....just glad i kept my 2000 out as my main use amiga.
Will have to wait til they have dried out now to see whats working and whats not.
Thanks for the kind messages.
edit: another casualty is my supradrive 500xp external drive for the a500....gutted
