In general:

Superlectron released two models. The company was well known for making pocket and desktop calculators since the early 1970s (some used nixie tubes). Later in 1976, their first game system, TV Challenger model 2000, model TVC-2000, was released. The next year, model 3000 came out, but used a GI AY-3-8500 chip instead of analog circuits. TVC-2000 played three games: Tennis, Hole in the Wall, and an amazing variant of the previous called Holes in the Walls where both players are transformed in a wall with a hole at the place of their paddle. Except Tennis, the other games feature an interesting wobble effect which makes both players oscillate up and down a little bit to increase the difficulty. Although the Hole in the Wall game play is obvious (put the ball in the hole), Holes in the Walls is different. The first wall has a partial hole and the second wall has a normal hole. Another very uncommon feature of this system is the scoring. The system case has two rows of numbers used for marking the scores, probably using plastic chips. A similar scoring method was used with the Videomaster Olympic. Other than that, the only difficulty level that can be changed is the ball speed. The system produces a unique beep when the ball bounces on a player.



Technology:

This system is analog and contains eleven chips of unknown type (their references have been rubbed). Like most systems designed with TTL / CMOS chips, vertical and horizontal holds can be adjusted because the analog circuits deliver video signals that are never precise, hence the need of adjusting them. The picture quality seems quite poor, but a better picture can be obtained by catching the composite video signal before the RF modulator. The system pictured here has a date sticker showing "20 OCT 1976" under the printed circuit board. It is also one of the first 5000 specimens produced. While the exact number produced is unknown, it is possible that not many were manufactured. Like most similar systems, it was hand assembled. As shown in the picture below, the assembly quality is quite poor.


- SUPERLECTRON 2000 GAMES -
Not Yet Pictured TENNIS:

Not much can be said for this game, except that it is implemented in its simplest form.
Not Yet Pictured HOLE IN THE WALL:

A classic variant played by analog systems.
The hole oscillates up and down a little bit due to the wobble effect, which increases the game difficulty.
Not Yet Pictured HOLES IN THE WALLS:

Yet another variant rarely seen.
Both holes wobble. First hole is different.

 


Circuit board. Eleven chips. Quite a poor quality...
