I have an ACA1232 I use with my ACA500, is this compatible with the ACA500+? Don't see any reason why it isn't but best to check!

Well I'll find out next year when my ACA500+ arrives.

From what I remember, the specs say that it is compatible with ACA12xx with the exception being ACA1230 which might not always work 100% due to the synchronous design.

Just read the description on icomp.de and the ACA1232 is 'Guaranteed' to work with ACA500+

Not bad for the price, 6x A500 speed, 8 mb RAM, and Hard disk. My only problem is that i don't like some pcb hanging out of the Amiga. They must invent some connector to turn around and put this inside the case

The same with all internal HDs on PCs and external HD cases for the Amiga. You have to open the case to change HD

When you use the feature to turn 512kB trapdoor $C00000 memory into chip mem, will the ACA put some of its own fast mem at $C00000?
What if you have a 1.8MB trapdoor expansion (with Gary adapter) located from $C00000? Will it work together with the ACA? If so, will the ACA still be able to turn 512kB of that into chipmem and then will the remaining 1.3MB then still be usable as slow mem? |

Re-mapping the lower 512k to $08 will not work, because the Gary-adapter does not know when a DMA access takes place, so it can't know when to switch to a different bank. You may be aware that only the later 1.8M expansion models with more specialized Gary-adapters had the possibility to use 512k as added chipram and 1.5M as fake-fast. These required running an extra line to the Agnus chip (or the solder jumper for the highest address line).

If you have a Megachip installed (2MB chip memory), will it be compatible with the ACA500 and ACA500 plus? With the chipmem switch disabled on the ACA of course.

If you have an ACA500 (plus) and an ACA12xx with the faster clockport, which one would provide better performance for a Rapidroad?

Are all of the software tools completed to allow configuration of attached ACA12xx accelerators? I have a 1221 (original model not ec) on my ACA500 with the beta firmware and I can't set the options on the 1221 although it is seen and it will display installed licenses.
I'm planning on attaching the 1233n to it eventually but with the software for it not completed yet... |

So performance wise, it would be better to just use the 512K onboard plus the 512K in the trapdoor, let the ACA500 plus convert the trapdoor, and use Chipmap?
