[Coco] Dragon snapshost first package

[Luis Antoniosi (CoCoDemus)]

Ciaran,

Do you have any handy routine to convert the FF00 PIA ROW from coco to
dragon ? I just need this to finish my patching.
I have one inside the os-9 but that one converts from Dragon to Coco, I
need the opposite way:

converts A from dragon32 to coco:

         pshs  b
         sta   ,-s        ; Save on stack
         tfr   a,b        ; Take a copy of keycode
         anda  #%01000000 ; Top row same on both machines
         andb  #%00000011 ; shift bottom 2 rows up 4 places
         lslb
         lslb
         lslb
         lslb
         pshs  b
         ora   ,s+        ; recombine rows
         puls  b
         andb  #%00111100 ; Shift middle 4 rows down 2 places
         lsrb
         lsrb
         pshs  b
         ora   ,s+        ; recombine rows
         puls  b
         rts
