If I remember correctly, IBM CGA screen memory starts at B800, 4 pages
of 25x80 characters, 2 bytes per character (including attribute).
That makes 25 x 80 x 2 x 4 bytes starting at B800:0000.

The IBM Monochrome adaptor starts at a different place.

See the IBM BASIC Reference Manual under BSAVE (and BLOAD) for a
sample code section to save and retrieve screens.  (I don't have mine
handy, sorry.)
