last year my A1200 died. After much troubleshooting it turned out that the clock battery in my 030+FPU card (I forget what brand, I think DKB) had leaked everywhere. I tried cleaning it up, no good! I took it to an amiga specialist who told me my only real option was to throw the useless thing away (the accelerator, not the A1200: which now works fine, albiet a bit slower).
Oh, I don't suppose you want to give/sell your 030 card to me instead of putting it in storage? :-D
