How to use emulator:
outside emulator:
+ "Memory mask" - special value for 040/060 MMU, used for fastest
memory work. You can use "0","1" or "x"(ignore bit) chars for input.
This mask copy to "Transparent Translation" registers according to
address of FastRam in your computer. For example, in A3000 64M ram
placed on $08000000-$0BFFFFFF, so mask equal 00001xxx and protect
area $08000000-$0FFFFFFF.
Refer to "Section 3 Memory Management Unit"
in M68040 User's Manual.

FastRam in your computer. Usualy used memory addresses and masks
are:
From: To: Mask:
40000000 7FFFFFFF 01xxxxxx ; CBSpeccy default
08000000 0BFFFFFF 00001xxx ; CBSpeccy default
07000000 07FFFFFF 00000111

Also your can use two different memory masks at the same time.
