[comp.sys.ibm.pc] CGA low resolution graphics programming

beyer@nick.egr.msu.edu (Don W Beyer) (01/28/88)

Hello world  (for you K&R fans out there :-)   )

I recently saw a game called moonbugs for the CGA that apparently used the
low resolution (160x100) 16 color graphics mode.  I am wondering if *anyone*
knows how to program (assembly) this mode.  I am led to believe that it is
not used much because it is not supported by the BIOS.  I need to know how 
to set up the MC6845's internal registers and the CGA video switch glue to
activate this mode.  Please, agonizing detail is requested. :-)

Unless you feel that this could be of interest to the rest of the usenet
community, please e-mail responses directly to me at:
