Could someone explain what happens when there is not enough memory on NeXTdimension board? Specifically, Does it swap to disk the same way 68040 swaps to disk? Does it support virtual memory? If not, what happens when we try to open too many windows (buffered)? If it does swapping, is the swapping activity managed via 040, and that is why it is slow? Thanks.
