Sphere, Inc. combined with another Colorado based company to become Spectrum Holobyte. This company would be a part of the Maxwell Empire. When Maxwell fell off a boat in Europe and disappeared chaos ensued for Spectrum Holobyte.

Eventually Gilman Louie appeared out of the remains to be Chairman of the board. Later Alameda based Spectrum Holobyte would acquire Microprose in 1993. Following that in 1996 it would acquire SimTex. This combined company of MicroProse, Spectrum Holobyte and SimTex would just become MicroProse. Failing in a bid to be bought by GT Interactive it would finally be bought by Hasbro Interactive at the end of 1998.

At the end of 1999 Hasbro announced the closure of the Alameda, Chapel Hill Studios.
