The Strange (and Rare) Videogame Pics Page


Basically an Amiga 500 in a slightly redesigned case (a Set top box with infra-red controller) and with a CD-Rom drive attached, it was probably the really first multimedia system ever released!
The complete name of the system is "Commodore Dinamic Total Television" and was an interesting piece of hardware: it was on this platform that many popular cd-rom games were originally developed (Sherlock Holmes Consulting Detective for example!). Psygnosis became the important software developer we all know developing their first cd-rom games like Microcosm and the never released Planetfall. The system was released in Europe and USA in 1991 with a 699.00 UK Pounds price tag. This system was the first real failure of the Commodore-Amiga venture. Multiple were the reasons of this failure: high price, not so high performances, few titles (and most of them were educational titles and not games!). It was also based on an old technology and had compatibility problems with many Amiga titles (unfortunately increased by the lack of built-in disk drive!).

The system and many optional peripherals.
