This constitutes a bibliography of some of the references used in creating
the PBClone library.  They are listed in no particular order.  I might note
that many of these references contain incorrect information on one point or
another and that they frequently contradict each other.  Such are the joys of
assembly programming.  Comments reflect my personal opinions on the text.



"The New Peter Norton Programmer's Guide to the IBM PC & PS/2".  2nd Ed,
1988, by Peter Norton and Richard Wilton.  Microsoft Press.
-- Often contains inadequate detail and is unusually error-prone.  Some of
   the information is unique to this source, however, so it has its value.

"COMPUTE!'s Mapping the IBM PC and PCjr".  1985, COMPUTE! Publications, Inc.
-- An old but indispensable reference.  The memory map, port reference, and
   low-level support chip information are very good.

"Programmer's Guide to PC & PS/2 Video Systems".  1987, by Richard Wilton.
Microsoft Press.
-- A terrific reference on video from MDA to VGA.  The example program for
   putting the Hercules adapter into graphics mode is rather buggy, however.

"The MS-DOS Encyclopedia".  1988.  Microsoft Press.
-- Encyclopedic it is.  Every serious assembly programmer should have a copy.
   Covers DOS itself, DOS interrupts, TSRs, communications, lots of handy
   articles by the best in the business.  The BIOS is ignored, however.

"Algorithms & Data Structures".  1986, by Niklaus Wirth.  Prentice-Hall, Inc.
-- Terse text with rather ghastly Modula-2 source listings.  One of the few
   places where sorting and data structures are covered even moderately well,
   however.  If you need to do sorts or b-trees, it's a mandatory text.
