If you can't find the internal ram expansion for the A570, Supra's RX500 is also compatible. I've run mine with upto 4 Megs of fast, never tried 8 Megs.
The 570 is compatible only with the original CPU clock rate, accelerators will dramatically shorten it's life, if they will boot with it at all. It does work fine with the 68010, but the marginal speed-up is hard to quantify outside of Sysinfo.
EDIT: It works with 2 Megs of chip, too.
