	The PC Junior was never really popular.  It was release at around 
the time of the 8088 (give or take two or three years) and had a colour 
screen, I beleive, which was like a big thing at the time.  I have only 
once seen one, and that was when my high school was sending old computers 
(//e's, TRS-80, an original XT) to the place where computers are 
eternally blessed.

	Don't worry about them.  By chosing DJGPP, you lose compatibility 
with anything below 386 (Why did I almost write that in hex?) processors, 
which the PC Jr certainly has.  This may be wildly inacurate, but my 
impression is that the PC Jr is a more gamerish XT. (I don't know where I 
got this idea, having never actually seen a PC Jr that was plugged in. :)
