Another workstation design under development at the time of the company's demise, the "PERQ 3B" was a colour model (sometimes referred to as the "PERQ 5") was taken over by Crosfield Electronics for its Crosfield Studio 9500 page layout workstation. The workstation was also known internally as Python, was developed in 1986 jointly by MegaScan and Conner Scelza Associates (both in Gibsonia, Pittsburgh) and the Crosfield team (in Hemel Hempstead, England). MegaScan, led by Brian Rosen, developed the workstation electronics and Conner Scelza Associates (led by Jerry Conner and Don Scelza) ported UNIX and wrote all the other supporting software. Crosfield (led by Andrew Chapman) were the overall project managers and had embedded engineers in MegaScan (Simon Butler and Mark Somervail) and Conner Scelza (Roger Willcocks).
