FDS anyone? Registers and flags
by Zepper on 2009-02-24 (#43679)
- Regarding a few registers and flags, here's what info I have:
Code:
   /* $4032: ?1???PRS
      S: Card set (1=ejected)
      R: Drive (0=ready)
      P: Write mode (1=disabled) */


$4032:0 is mirror of $4030:7?
$4032:1 is mirror of $4025:6?
$4032:2 is mirror of $4025:2?

- Could someone clarify this thing?
