No I sait Slow RAM. The ACA500 use the $C00000 address space for it's embedded memory. It's slow RAM, not fast RAM. It's why you can't use expansion card to the trap door w/o conflicts. (except if the A500 is hacked to use it as chip RAM)
So, you have to buy an ACA12XX card to get real Fast RAM.
The Zeus68K embed FAST RAM.
