I don't have daughtercard on this thing.. Why you ask?
Because on NTSC/North American systems, we have problems with a lot of sidecar expansions due to the PAL's being slower and not grounded very well on the daughtercards. For instance, it's pretty common on an expansion like yours, that it might not work. Anything with RAM expansion over 2mb, and the A1000 expansion bus likes to choke and exhibit all sorts of strange problems. HD errors, wrong RAM values, etc.
