    I`ve  scraped the idea of the tutorial,  it was crap  and  lame!   So 
 instead I`ll just include a few sources each month (I make the deadline) 
 and  also continue to attempt to answer any problems.   This  month  I`m 
 kicking off with my GFA infinite sprites screen and my mini-dister:


 Extracting files
 ================
    Simply  copy DISTER.TOS into a DISTER folder on a  blank  disk,  copy 
 INF_SPRT.TOS into an INT_SPRT folder on a black disk,  then run the  two 
 programs.   The  first should extract about eight files and  the  second 
 about three files.


 Infinite Sprites
 ================
    Firstly,  acknowledgements must go to Dream State (Trantor),  also of 
 Virtual Infinity, for explaining the basic theory.  My interpretation of 
 the screen literally is *infinite* - well, until the radius overflows!
    All grafix and musyc data is contained within the data file.  I coded 
 this screen on a b & w TV using a color pallette,  so I hope it looks OK 
 in color!


 Mini-Dister
 ===========
    The  grafix in these three screens is of me (Professor)!   The  photo 
 was taken by 68K,  of Virtual Infinity,  at the Wembly 16 bit show  this 
 year (1993).  Acknowledgements also go to 68K for scanning.
    Sorry they all use the same musyc, but it`s so all data can come from 
 a  single data file.   The screens aren`t quite as fast as I would  have 
 liked,  but still very impressive considering no assembly knowledge  was 
 required.
    Please be patient with DISTER3, with over 352 thousand pixels to pre-
 calculate you can`t really blame GFA for taking it`s time,  I just  hope 
 it can run on a 1/2 meg!  I don`t actually think DISTER3 can be achieved 
 in real-time, and challenge 68k coders to prove me wrong!


 WARNING
 =======
    The  VBI musyc replay routine is written by Dream State and I`ve  not 
 fully documented it in my sources.  If you wish to use it, please DO NOT 
 attempt to hack it out my data files.   Please get in touch with  either 
 me or Dream State for full information.


 Next Month ...
 ==============
    Hopefully coming up will be a GFA,  Degas '.PC?' image  decompressor.  
 But I wouldn`t hold your breath,  I`ve made promises in the past and not 
 kept to them!


 Contacting Me
 =============
    If  you  have a GFA problem,  or want further  information  about  my 
 sources,  I (Professor) can be contacted:  by post,  by mail, via Ictari 
 and via STAMP on Monochrome.
