I had got this ploblem when i bought my A3000. The super denise 8373 is easy to find but the Agnus 8372"AB" or "B" is hard to find, finally i must buy that in ebay in the States. So while you find one you can fit a 8372A with no jumper modification (I was while) in spite off this agnus is a 1MB in my 3000D only find 512 Kb (there is 2 Mb) but system worked. Finally find a 8372B and all it's ok. and the same is for the denise put an OCS Denise while.
