At the moment, the Royal Swedish Library (KB) has opened their magazine search engine as a benefit to all bored, self-isolating people. I've made a number of searches on topics that otherwise are near impossible to find information on the Internet, but it turns out the magazine archive is full of info.
Dagens Industri (September 14, 1983) has a small blurb:
Creativision dator, som introduceras av Elof Hansson i Göteborg har i grundutförande 8-bit CPU, 16 färger, grafik med 256x192 punkter, tre tongeneratorer, 16 kB primärminne varav 11 kB användarminne, 2 MHz klockfrekvens, Basictolk och uttag för bandkassettminne. Creativision-datorn kan förses med bl.a. utökat primärminne - max 64 kB, seriellt/parallellt I/O-interface för t.ex. skrivare, plotter, diskettstation, telefonmodem och separat tangentbord.
Nothing new here - they got pretty much the entire spec in a few lines though I'm not sure about the 16K RAM of which 11K is available for the user. Is that the result of the BASIC cartridge storing programs in VRAM?
Expressen (October 9, 1983) has an overview of the growing home computer market, focusing on TI-99/4A, Colour Genie, Atari 600XL, Luxor ABC-80, Dragon 32 (with a picture of another computer which is not
a Dragon 32!), Commodore 64, ZX Spectrum, VIC-20, ZX-81, Atari 400 and Spectravideo SVI-318 but also makes a note in the passing that you might also want to look at Oric, Laser, Jupiter, Microprofessor, Sord, Radio Shack, Komtek and CreatiVision.
Dagens Nyheter (November 11, 1983) in the classifieds has a Creativision 16K for sale, with tape recorder, BASIC and 4 games. Price as new 4500 SEK, now only 3500 SEK after 2 months of use.
Dagens Nyheter (November 14, 1984) has another Creativision for sale in the classifieds. This time you get it with tape recorder and 9 games for 1800 SEK.
Dagens Nyheter (November 15, 1984) has yet another Creativision for sale, with 4 games. Price as new 4000 SEK, now only 1000 SEK!! The same seller advertised also the next day.
Unfortunately that was all I could find, one short article, one mention in an overview and three sad people wanting to sell their Creativision systems. By November 1984 obviously it was cold like an ice cube, people almost would give it away.
