BTW, older A3000s might need Agnus upgraded to a 8372B in order to address 2Mb chip mem.
I've never seen an A3000 with anything other than an 8372B, and I have an original model with the Superkickstart here, so it seems like if any would have been sent that way, it would have been an early one. AFAIK, all A3000s shipped with full ECS and the 2meg Agnus version.
The models that didn't have 2 megs of CHIP ram had 8 256x4 DIPs for CHIP ram (left side of the motherboard), and 8 256x4 DIPS for FAST ram (far right side of the motherboard, below the empty ZIP sockets). Moving those 8 DIPs from the right side sockets to the empty ones on the left (next to the current CHIP RAM) gives 2 megs CHIP RAM, and SHOULD have been the standard procedure whenever adding ZIP ram to the 3000. If those DIPs are totally missing from your A3000, you'll need to find 8 matched DIPs of the same or compatible part # as your CHIP ram.
