I have this Amiga500-Plus machine. And if I put a 512k expansion in the trapdoor, it gives 1.5mb Chip. The same with a 1mb expansion, gives 2mb Chip Ram in total. Then I have this a512 expansion. The question is. As the a512 have a passthrough port. Can I extend it with whatever expansion I want? Like if I attach a BooBip expansion after the a512. Will I then get 1mb extra Chip and 512k Slowmem. Like 1mb Chip from expansion plus 512k Ranger upgrade? Or do I need 3xa512 in one row, in order to achieve 2mb Chip plus 512k Slow in total, on an Amiga500-Plus?
