Hi,

I don't understand what's the actual effect of LMPR's 6th bit, called
RAM0. It's explained on page 18 of the technical manual.

For example, what' the difference between this:

----8<----------------------------------------------------------
  ld a,023h     ; bits 0-4: RAM page 3; bit 5: RAM0 
  out (0fah),a  ; allocate pages 3 & 4 to section A
----8<----------------------------------------------------------

and this?:

----8<----------------------------------------------------------
  ld a,003h     ; bits 0-4: RAM page 3;
  out (0fah),a  ; allocate pages 3 & 4 to section A
----8<----------------------------------------------------------

Is the bit needed in order to make the system know ROM0 is paged out?
Does it have to be set always for allocating a RAM page to section A?

Thank you
Marcos
