Both Commodore and Escom have made all kinds of mistakes when assembling the A1200. They all have in common that timing fixes that were required for very early Budgie revisions have been applied, although Budgie was already the new version.

To put it simple, your board will not be stable with any accelerator if one of these four components is assembled: E123C, E125C, E121C and E122C. All of them are located on the bottom side if the A1200. You won't get around opening the computer and checking yourself if these components are assembled. The revision number of your board says nothing. The year of your board also doesn't give any information. The one and only thing you can do is to check your board.
