[depuck@ulster.net (Timothy T)]

Hi i need some help.. i just got an apple2 gs(running system 5.0) for my
son it has (2)  3.5 flopy drives & (1) 5.25 flopy.
   
   I have d/l some files from the web and they are stuffed  with .sdk .shk. bxy


 I d/l the files from different web sites om my 6040 (68k) mac I cant get
any of them to open so i can put them on a 800k flopy and then use them on
the Apple 2 GS.

   what should i use to open the files  that end in .sdk .shk  .bxy



                        thanks, Timothy T
