1940/1942 Reference

This monitor is a 13-inch bisync (not true multisync) monitor built by Samsung for Commodore. It has two ranges of sync frequencies to match both normal (15.75 kHz) and doubled screen modes. The 1942 differs from the 1940 only in that it has a smaller dot pitch. MonEd may be useful in getting the picture to fill the entire screen (the 1942 came with a set of patched  monitor drivers). Both variations feature stereo speakers.
