It was a leading computer series called Tandy 1000 with 16 colors and 3 voice sounds. Tandy graphics which were compatible with most pc games. From 1986 until 1991 they were considered as the best graphics (much better than common IBM compatible PC's) until VGA and soundblaster took over, rendering Tandy obsolete. It was a bit better than EGA.....
However IBM compatible pc's could run games on Tandy graphics but the result is not the expected one...it looked like CGA or Hercules heehehhehe all purple
