  This directory contains the OEM-specific TMS340 Graphics Library files
  that have been ported to Texas Instrument's TMS34020 Software
  Development Board (SDB).  The 34020 SDB port currently supports the
  following 18 graphics modes:

   mode #  resolution  # colors  # pages  monitor

  All graphics modes drive noninterlaced displays.

  Subdirectory \OEMPRIMS contains the hardware-specific TMS340 Graphics
  Library functions that have been ported to the 34020 SDB.  Subdirectory
  \DEMOS contains a series of demonstration programs that run on the
  34020 SDB.  To view the demos (assuming you have installed the 34020
  SDB on your system) change to the \DEMOS subdirectory and run the batch
  file DEMO.BAT.

  Note that the GSPL.EXE COFF loader utility program in the \DEMOS
  subdirectory has been configured for 16-bit data transfers through PC
  memory segment 0xD000.  If this segment in your system contains
  peripherals configured for 8-bit transfers, you will need to do one
  of the following:

    1.	Reconfigure the gspl utility for 8-bit transfers through the
	34020 SDB.  The gspl utility is reconfigured by invoking it with
	the "-c" command-line option.  If you need more information on
	this utility, refer to the GSPL.DOC file in the main library
	directory.

    2.	Reconfigure the peripherals in segment 0xD000 for 16-bit
	transfers.

    3.	Relocate the 34020 SDB in another segment in which all
	peripherals are configured for 16-bit transfers.
