Christensen was noted for building software tools for his needs. He wrote a cassette-based operating system before floppies and hard disks were common. When he lost track of the source code for some programs he wrote ReSource, an iterative disassembler for the Intel 8080, to help him regenerate the source code.
When he needed to send files to Randy Suess he wrote XMODEM. Christensen worked at International Business Machines Corporation from 1968 until his retirement in 2012.
His last position with International Business Machines Corporation was field technical sales specialist.
Christensen received two 1992 Dvorak Awards for Excellence in Telecommunications, one with Randy Suess for developing the first Bulletin Board System, and a lifetime achievement award "for outstanding contributions to Personal Computer telecommunications." In 1993 he received the Pioneer Award from the Electronic Frontier Foundation.
