SV-603 - ColecoVision Game Adapter is an accessory that could be purchased with SpectraVideo computer. I enables you to play ColecoVision cartridge games, but ColecoVision console was considered the best home option to play computer games at Arcade quality.  This adapter easily hooks up to the SV-318 og SV-329.

Here are some cartridges that was used in Spectravideo computers and we got them with our SV-328mkII. Three games : Sector Alpha, Flipper Slipper and Frantic Freddy.

Also we got JustWrite Jr which is a Word Processor program and with a Norwegian language addon.

And this is what an Cartridge looks like inside, just two small chips :)

With our Spectravideo SV-328 computer we got alot of various games and software on cassettes. Some of them are in their original package with the manuals, but most are just the cassettes themselves. Spectravideo used both cassettes and cartridges for their games. Their selection of titles where not as good as Commodore 64, Atari, Apple and others, but you can still find some gems hidden in there. The first year though only a handful of various games and other programs was available.

​The SV-328 is an 8-bit home computer introduced by Spectravideo in June 1983. It was the business-targeted model of the Spectravideo range, sporting a rather crowded full-travel keyboard with numeric keypad. It had 80 kB RAM (64 kB available for software, remaining 16 kB video memory), a respectable amount for its time. Other than the keyboard and RAM, this machine was identical to its little brother, the SV-318.

​The SV-328 is the design on which the MSX standard was based. Spectravideo's MSX-compliant successor to the 328, the SV-728, looks almost identical, the only immediately noticeable differences being a larger cartridge slot in the central position (to fit MSX standard cartridges), lighter shaded keyboard and the MSX badging.

​Reference to the operating system Microsoft Extended BASIC is not to be confused with MSX BASIC, although some marketing at the time claimed that Microsoft Extended is what MSX stood for.
