Yes, I remember similar ones, in those days when there were Dandy and Sega consoles, there were rumors about such computers. At that time, I had our analogue Sinclair Spectrum ZX81,

which was connected to a black-and-white TV

and I downloaded data from a tape recorder.

How I miss those days. I finished my studies and sold that computer. I really regretted that. Two years ago, I saw the same thing at a garage sale.
