Rare hard-to-find monitor cable for Teknika MJ-22 monitor for Commodore 128 computer in 80-column mode. Not for Magnavox 80 column color RGB monitors. Also does not work on Commodore-branded RGB monitors (which usually require the Magnavox RGB cable). Approximately 4 ft. long. Ideal for use on the Commodore 128 and 128D computer. Also compatible with older IBM compatible PCs having 9-pin CGA (color) outputs going to a Teknika MJ22 (80-column) color monitor (having an 8-pin DIN input). Not for use with monochrome (non-color) TTL Magnavox 80 (or other branded) monitors or with PCs having 9-pin monochrome (non-color) outputs. Despite being unused (NOS-- new older stock) cables the cable you receive may be slightly (but not significantly) smudged.Note: When using the Commodore 128 or 128D computer in 80-column mode please make sure that the 40/80 key on the keyboard is pressed down. Also, make sure that the switch on the monitor is selected for RGB 80 column mode.
