Background: Digital Research Computers/Corporation or DRC of Texas was a small manufacturer of S-100 cards and systems. They are NOT associated with Digital Research Inc or DRI of California, founded by Dr. Gary Kildall, creator of CP/M. I recall ads in the magazines of the era which described the company as "DRC of Texas". - Herb
