GDRI

As Randy told Keith Smith, two other people who helped in the early days of the company were Doug Hughes (former Atari engineer) as well as John and Christie Liljestrand (draftsman, bookkeeper). All worked on a contract basis.

I wasn't sure if Hughes worked for Taito America or Threshold Research. The post here says he worked for Taito America: http://allincolorforaquarter.blogspot.com/2014/07/the-pre-history-of-night-driver-part-3.html …
