General info on the purpose of this disc...

Its dead simple really.....just boot up this disc, choose which level of
  Dungeon Master you'd like to see/view/do/die in, press the appropriate
  key and wait for the relevant file { DMGame.dat } to be copied over to
  the root directory so that the Dung Mast game disc knows what or where
  you want to do or see { or die in !!! }

THE IMPORTANT BIT :-
~~~ ~~~~~~~~~ ~~~ ~~
After the copying has finished just boot up the DungMast game and RESUME
  with this disc as your saved game disc.
You will, of course, have to write_enable this disc [ thats with NO hole
  showing ] to be able to copy the saved games.

END OF THE IMPORTANT BIT.

I hate those big_headed foreign plonkers who delight in spreading virii
  { is that spelt rite ? }  so I have used only those commands commonly
  found  { such as those on the WorkBench disc }.  Search for any virus
  if you wish but you wont { I hope ! } find any.

        T H E   A. P. H. I. D!  I S   T R U S T W O R T H Y ....

However...I'd keep a backup of this disc just in case...........

All my love to the gorgeous Jane Elizabeth and
