Thalamus Ltd (also known as Thalamus) was a British computer game developer that published titles for a number of 8-bit and 16-bit platforms during the late 1980s and early 1990s.
Thalamus Ltd was created in 1986 as an in-house software publishing label of British magazine publisher Newsfield Publications Ltd, to take advantage of their leading position publishing computer game magazines, such as Crash and Zzap!64, during the mid-1980s. Ex-Activision PR Manager Andrew Wright was assigned the position of Company Director and Newsfield staff writer Gary Liddon was appointed Technical Executive. The company was initially based in Canonbury, North London, in an office shared with staff of Newsfield's newly launched lifestyle magazine LM.
Thalamus capitalised on the success of the Commodore 64 gaming scene by releasing their first batch of titles on this platform. Having established numerous contacts within the C64 development scene through the popularity of their Zzap!64 gaming magazine, Thalamus were able to sign up Finnish programmer Stavros Fasoulas to develop their first three titles, Sanxion, Delta and Quedex. Sanxion was the first release to bear the Thalamus name, and it garnered a Sizzler rating from Zzap!64 - this led to accusations of favouritism from rival publication Commodore User. Rob Hubbard provided the music for the first two titles, while Matt Gray provided the music for Quedex. "Thalamusik", the loading tune that accompanied the C64 version of Sanxion proved to be so popular amongst fans that Zzap!64 later included a full synthesised version on one of their cover cassettes.
