Siera Electronics is a manufacturer of electronic and audio equipment that was founded in the Netherlands but is now based in Belgium (source : The Odyssey² Homepage) . Siera distributed Videopac systems and games (where ? Belgium?) under its own company name.
The Siera G7000 is only a Philips Videopac G7000 rebadged with the Siera logo. Siera also released the Philips Videopac G7400 under its own brand.
Nearly nothing is known about Siera... See Videopac G7000 entry for more details.
