DOS & UNIX co-existance

[Andrew Gallo]

	I am the current owner of a DOS PC/XT.  For a solid Unix 
machine, what are the sort of "bare minimum" system requirements I'll 
need?  
	Also, can my DOS applications co-exist with Unix?  Ie. can I,
at boot time, decide which OS to load?
	Being certain that these questions have been asked 1000+ times
before, I thank you for your responses and your patience.
