[comp.sys.ibm.pc] Cheap source for DOS clones?

warn@druhi.ATT.COM (WarnerD) (05/05/89)

A friend asked me about source for DOS or compatible clones.  He's
interested in purchasing source to achieve INT 21 compatibility for
some kind of turnkey application and would like to avoid the $100K or
so purchase from the "well-knowns" e.g. Microsoft, DR.
I don't normally find the time to wade through all the postings to this
group so please respond to me by mail or by phone to my friend directly
(Don Kehn at 303-449-1110).
Thanks in advance for any info.
