ALTAIRZ80: Fixes problem with MEM dump command

Browse source 
The MEM dump command would not display past SET CPU xK memory
size. This prevented displaying ROMs or other RAM windows when
a lower amount of memory was specified. This PR changes MEM to
always display a minimum of a 64K regardless of main RAM size.
