NO!  NO!  NO!   This is net.atari8 for the 800/400/1200XL/800XL/600XL/130XE 
8 bit computer line of Atari.  We do not know or care about the 16 bit line
of computers (520ST, 1045ST, etc.).  Please post ST questions to
net.micro.atari16!!!!!

It took a long time to split the groups, now use them properly!

Grhhhhh!!!!!
