TTL based tennis game kit

[reagle]

Stumbled on this thing on tindie. That's one huge kit to build, but I do like the TTL-only aspect of it!

Nice, I'd like something like that. Not sure I could afford one though.

Hm, that isn't clone of the original as the name suggests...

I am old enough to remember the original design, UK wise, was called "Ping-Pong"

I attempted to build one in early nineties, using a Soviet clone of an IC specifically designed for this application. Not sure if it was myself or the clone part but it never worked

On Dr. Hugo Holden's Electronics website he describes the circuit in a superb 100 page Pdf entitled "ATARI PONG E CIRCUIT ANALYSIS & LAWN TENNIS:"

I wonder how close this is to the original board...  I believe it was also created mostly using logic chips.

I remember back in the day when I used to repair these sorts of arcade games (nearly 40 years ago!), there was little documentation from the manufacturer apart from circuit diagrams and parts lists.
There were a couple of companies that produced service guides and explanations of how they worked for the service industry. Very helpful for those brought up on analogue electronics and needing a leg up to the digital side.
