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 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 buggy.  The little bit
   it had of value has been superceded by more current works.  Garbage.

"COMPUTE!'s Mapping the IBM PC and PCjr".  1985, COMPUTE! Publications, Inc.
-- An old but still handy 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, if getting a bit dated.  Still, its coverage of DOS is
   excellent.  Recommended for serious assembly language programmers.

"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.

"The Programmer's PC Sourcebook".  2nd Ed, 1991, by Thom Hogan.  Microsoft
Press.
-- An astonishing collection of data and tables.  With comprehensive scope
   but no depth, this reference can tease by providing insufficient detail.
   Still, a priceless work.  Get one immediately.

"Microsoft MS-DOS Programmer's Reference".  1991.  Microsoft Press.
-- Although books by Microsoft Press seem to have an unusual number of bugs,
   they are usually otherwise excellent.  This one stinks.  It lacks vital
   details, contains many serious bugs, and offers smugly hypocritical advice
   on program design.  I haven't seen as much info on the DOS 5.0 National
   Language Support elsewhere, though, so it may make a tolerable last choice
   if you want to go international.  Don't say I didn't warn you.

"Sound Blaster: The Official Book".  1993.  McGraw-Hill, Inc.
-- Not as complete as one might like. Most of the book is concerned with
   idiot-level end-user stuff. An appendix details the hardware interface in
   an ineffectual manner, and the SB software drivers in a manner which is
   mostly sufficient for technical folks.
