Special Super Denise in A3000?

[mechy]

If i'm understanding you right here is my take on it... The super denise in the 3000 is a ECS denise, the A2000 in most cases is not ecs(some were) and that might explain why the 2000 denise doesn't work. The A500+ may of also had a regular denise chip and not ECS.. compare part numbers. were they all 8373.just a guess but the A500+ was a pal machine and the A3000 is switchable.. i would think this would mainly affect agnus,but maybe a clue to why the denise doesn't work so take it with a grain of salt( i have absolutely no proof on this).

I have used the ECS denise from a A3000 in the 2000 though with the right agnus.
Plugging the 8373 into the 1000 makes for some purdy colors and artifacts if memory serves..problem is you can't change the A1000 agnus since its dip and not plcc.
If all the chips are indeed 8373 ECS super denise,then maybe the A3000 agnus was swapped out wrong or is a early one?Not 100% sure this would affect it,but i have seen some odd stuff with A3000 chip revisions.Its not unreasonable to think there might be chip compatibility problems in the bazillion revisions thru the A3000's life.

With a Commodore A3630 board installed, an Amiga 2000 becomes a 32-bit machine.  Also, keep in mind, there is really not that much difference between 24-bit (Amiga 2000) and 32-bit (Amiga 3000).  In fact, did you know that an Amiga 2000 with an 030 board installed actually runs faster then an Amiga 3000 with an 030?

I assume you meant a A2630??? the 3630 is not for the 2000.and the zorro bus is still NOT 32bit even with a accelerator.
there is quite a bit difference speed wise from the A2000 to 3000. the 2000 will always have slower zorro2,while the 3000 has zorro3.
Of course there are some A2000 accelerators with 030/50,of course it beats a stock 3000/25 but if u want to compare accelerators,the A3000 with a cyberstorm ppc still wins. silly comparison.

comparing stock machines is no contest. comparing only cpu speed is not usefull either ,stick a z2 gfx card in that 2000 and compare it with a z3 gfx card in the 3000...
