hohiro: Still this thing had most likely a 5.25" diskette drive and a joystick, so for me its more an old homecomputer. Most consoles of that time already had joypads and the Atari 2600 and such are a bit too old and didnt have a keyboard afaik.
Yes. From the data we have so far, everything points to an IBM PC (286 or 386) that the OP may have mistaken for a console when he was a kid.
Particularly:
- 5.25" floppies were a typical medium for IBM PCs of the 80s (and into the 90s, for compatibility). While there have been consoles that used such floppies, they would have been extremely exotic in Central Europe at this time.
- Keyboards, especially as separate devices which had to be connected to the main machine, were typical for IBM PCs. Almost all home computers had their keyboards as a part of the machine's case. Consoles of the time usually did not have keyboards at all. There were exceptions to both of my last statements, but again, having those in a Central European household in the 90s would have been very unusual.
- A game like a Danish version of "Wheel of Fortune" would not have been produced for a machine that was exotic in Denmark at that time. That rules out the exotic alternatives and leaves an IBM PC as the most likely option. (Note: I searched the net for 'Lykkehjulet' and 'Computerspil', but did not find anything worth mentioning. My search abilities are limited because I don't speak Danish.)
Caveats:
- I have very little knowledge about the state of Apple computers at that time, so I can't tell if that's a possibility too. If I remember correctly, then most non-IBM personal computers at that time were using 3.5" floppies though.
- It would be unusual for an IBM PC to be connected to a TV instead of a monitor. I suppose that TV adapters for IBM PCs did exist, and may have been an option for users who did not want to spend money on a monitor, but it would have been unusual.
Some searching shows that there _were_ so-called RF modulators which allowed users to connect an
Apple II to a TV, and the Apple II also used a 5.25" floppy. The keyboard was on the case, though, so unless the OP mistook the floppy drive for the "console", and the Apple II case for the "keyboard", then this is not a perfect fit either.
