The highest resolutions the PCjr would do were 320x200x16 or 640x200x4. These video modes were specific to the PCjr with 128k installed. The video port on the PCjr used a TTL RGBI interface that sported 8 colors with two intensity levels. The MCGA modes were introduced with the PS/2 Model 30. -- tba...@tomspc.oau.org (Thomas Baker)
