History

[edit]

UniSoft was founded on October 5, 1981, inEmeryville, California.[1] Their original business wasUnix development, and they were soon recognized as one of the early implementers of Unix for the emerging 16-bit microcomputer market.[2] By 1989, they had completed over 225 Unix implementations on various hardware platforms, which was estimated to have been about 65% of all such ports.[3][4] UniSoft's port ofVersion 7 Unix was the first operating system forSun Microsystems'Sun-1 workstations and servers.[5] It also developedApple Inc.'s Unix variant,A/UX, for the AppleMacintosh II.[6]

Uniplus+ was a commercial version of theUnixSystem III andSystem V operating systems that was available in the 1980s. It ran on theMC68000 Motorola chipset onTorch Triple X, theApple Lisa, among other machines.[7] It served as the basis ofSilicon Graphics'GL2 operating system, which eventually evolved intoIRIX.[8]

In 1991, the company moved to its current offices inMillbrae, California.[1] Although seeking to enter the market for Unix products on RISC-based systems, such as a version ofSystem V Release 4 for MIPS,[9] the company was unable to maintain the same level of revenue as it had in targeting the 68000 family, eventually leading to a restructuring of the company ownership and a shift towards testing and verification suite development.[10] UniSoft shifted its focus to thetelevision industry in 1997, in order to address standards compliant software in that market. It now works solely in development, testing, and broadcast tools for digital television.[4]
