Newsflash from the development lab: Blizzard accelerators don't work. They use a ROM start is launched very early in the startup-process, and the ACA500 can't do anything about that. It appears like the B1230-IV doesn't like something of the A500 and crashes if fastmem is installed. It works if you remove the SIMM, but that's not a really usable configuration.
Since other Blizzard accelerators also use a $f0 ROM, it is highly unlikely that they will work. So far, only ACA1231 and ACA1232 work. The ACA1230 doesn't work due to syncronisation problems (that I probably won't be able to resolve) and the ACA1220 currently also does not work (caution: This is not permanent, but just a development snapshot).
Apollo 1240/1260 have a design fault in 16-bit accesses, and the ACA500 is 16-bit all over, so that fails "by design". What may work is Apollo 020/030 accelerators, but I don't have any working samples of those.
Syncronous designs like M-Tec will most likely not work due to the same syncronisation trouble that I have with the ACA1230.

I'm sorry to report that I have removed the IDE port from the current concept. CF cards grow at Moore's law, and you can already fit all the Aminet CDs on one CF-card. It won't take long until we have the first CF card that exceeds the size of all available Amiga software. What's the current size of back2roots? I think it's around 1TB, right?
I'm currently working on a full re-design of the ACA500, because the current mechanical concept has failed the "installation by girlfriend" test.
