Ah, this one has some interesting history. VTech (Video Technology, Ltd.) from Hong Kong sold this as a VTech Lazer 200, as the Salora Fellow in Scandinavia, the Texet TX800 in the UK, and as the Dick Smith VZ200 in Australia from 1983-1985. Dick Smith sold over 200,000 of these. It used an audio cassette recorder for loading and saving programs and used a TV for the display. It included Microsoft BASIC in ROM. The VZ200 enthusiast WWW site is here.
