New for project page:

1. If you need to save and restore video buffers,
        in VGA mode, PERHAPS you can invoke int 10h, fcn=1c.
   I am not sure yet...

        See Helppc:
        Subfcn, AL=0: get save buffer size
                CX=requested states ???
                On RETURN:
                        AL=1C
                        BX=buffer size in 64 byte blocks

        Subfcn, AL=1: save requested state
                CX=requested state ???
                ES:BX=pointer to buffer
                RETURNS nothing.
        Subfcn, AL=2: restore requested state
                similar to AL=1.

        Q: does this mean that we can directory save
                the video buffer contents?


2. Write a simple routine in mode 10h
	to alternately display between two pages.

3. Write a simple routine in mode 12h
	to illustrate various logical functions
	(AND, OR, etc) on video buffer.
