Technical Design Labs was also known as Trenton Design Labs, TDL, and later Computer Design Labs. Founded in the Trenton & Princeton, New Jersey area in the mid-1970's, they produced 8080 and Z80 software, and S-100 cards and systems. Their first S-100 products included a 16K memory card and a Z-80 card, competed in July 1976 and advertized in BYTE that November. Some TDL system software evolved into software for Epson's popular QX-10 personal computer. TDL's Roger Amidon produced a popular ROM monitor called Apple (for the 8080 version) and Zapple (for the Z80 version). Check my Web page on the Zapple monitor for details and recovered sources and binaries. - Herb Johnson
TDL founder Carl Galletti, now a top Internet marketer, currently lives in Sedona, Arizona. He described the origins of the "S-100" name to me in 2007.
TDL partner/owner Roger Amidon designed many TDL products.
