[comp.sys.ibm.pc] Hercules Graphics question

schneck@sunybcs.UUCP (05/25/87)

Disclaimer/Apology:
With all due apologies for not reading the thousands of past articles,
some of which may have contained the answer to the following question.

How can I get the Hercules graphics card to run in 720 x 348 graphics
mode?  I have the 6845 register settings, but that alone is not doing
the trick.

[ I want to write some graphics routines to do such mundane
  things as drawing lines, circles, etc.  I don't mind starting with simply
  turning on pixel-by-pixel *gasp*. ]

A nice "from-scratch" tutorial would be appreciated.
(Source code -- C, assembly, or otherwise -- would be even nicer.)

		Thanks,
		  Nelson
