Make-It-Yourself projects
Electronics Australia, may 1976
This article features an interesting project
designed with a some TTL chips (of the 74XX family) used in analog mode. Because
some parts of the whole design are analog, one or a few electronic components
were used to featured uncommon effects in the games.
The system plays a two-player game which can be varied in several ways. The most
common variant is the inversion a paddle to obtain a vertical line with a hole.
Then, the system can let a paddle (or hole) wobble to increase the game
difficulty.
There is also a quite unique optional interaction between both players which is
such that when one moves his paddle
or hole, the other paddle or hole will move a little bit. By combining these options,
a total of 32 variants. More can be obtained by placing one or two holes at specific locations. Here again, this article shows
how to make several variants of a same game with a few classic logic chips.

If you want to build the game, you will want to view a larger version of the circuit board implementation layout as seen in Page 41. |
