will this work with aca500plus?
Yes, of course.

One of the next things to test is a similar kind of IDE speeder on the ACA1240/1260. Since the ACA1233n-55 has rather limited logic, only two speeds were implemented (PIO mode 3 and 4), but the ACA1240/1260 can implement much finer granularity in terms of timing, so we can push/relax timing much better. Still, this may require a buffered adapter or high-quality CF card to work reliably. I've had great results with a buffered IDE adapter and a physical IDE drive (old IBM 16G drive), as that was MUCH faster than any CF card or DOM that I could find (>10MB/s).
On-board IDE is not planned. I don't want contraptions with a wobbly CF card adapter on such an expensive card.
Would be great if the ACA1260 would have faster IDE speeder than the ACA1233n-55.
I had also mixed results with the IDE speeder on the ACA1233n-55 with the A1200. With the SanDisk Ultra CF 16GB 30MB/s I have around 2.6MB/s and with the SanDisk Ultra CF 32GB 50MB/s. Which works the best with my AOS 3.1.4..1 BestClassicWB 1.5 and AOS 3.1.4.1 BestWB 1.3 with FFS. The SanDisk Ultra II CF 8GB 15MB/s is the fastest around 3.4MB/s but that speed I can only have with AOS 3.1 BetterWB 4.3.
The ACA1233n-55 with the ACA500Plus V2 I have around 6.9MB/s with a SanDisk Ultra CF 16GB 30MB/s card. With AOS 3.1.4.1 BestClassicWB 1.5 and BestWB 1.3.
How fast would be a CF card with the ACA1260 with the A1200. Have the IDE speeder also have speed difference with AOS 3.1 and AOS 3.1.4.1 such as the ACA1233n-55. The ACA1260 is nice to have on the ACA500Plus V2 but would like it more on the A1200 for the AGA 060 Demos.

While I think you plain forgot to activate the IDE speeder if you're only getting 2.6MB/s, it's plain impossible to reach 50MB/s.
I can't tell what speed you can get in the end with the ACA1240/1260, as it heavily depends on the CF card and the software. We may even add an IDE-fix-like package to the software in order to get the best-possible speeds. That said, the original IDE-fix package might be worth looking at for you, as that will also take serious advantage of the IDE speeder of your 55MHz card.

Jens, you read it wrong.
Use these SanDisk Ultra CF 32GB 50MB/s card with the A1200. -

The IDE speeder on the ACA1233n-55 is activate with ACAtool 2.4. See now that there is a newer 2.5.1 version. Maybe that work.

Sounds good, as long as higher IDE speed can be obtained I'm happy. Higher IDE speed makes a very noticeable difference in usage. I wouldn't mind using a buffered adapter, even though I think my Transcend PATA SSD should give good performance without it.
Also curious to see other expansion options, RTG in conjunction with an indivision AGA MK3 enabling a single output on RGB and RTG would be awesome too. I will sit patiently (okay, somewhat excited) until the card comes out!
