The Super Video Graphics Array (SVGA), 640 X 480 pixel sl , 256 shades of grey, capability should be adequate. Also to be considered would be 4-8 bytes of memory on the PC to be used with "windows". The CD ROMS should work well on the CD ROM players without any additional software. Bruce H. USGS-NMD-OIS-BESI-ESIMS MS 509 BITNET%"BHUBBARD@USGSRESV"
