https://en.wikipedia.org/wiki/Pong https://en.wikipedia.org/wiki/Pong states "TTL logic" with later IC versions for consumer mass production, whereas the subcircuits in this demonstration state "analog". Well, I guess everything's analog if you look at it that way. Certainly logic ICs are a long way from pure analog.

- dboreham 4y agoHuh? TFA states "It was a circuit, implemented mostly using digital logic chips, with a few timers and other analog components." and provides schematics from which all the components can be identified as digital (74xx) or analog.
- not2b 4y agoTTL was digital logic, chips that do boolean functions or that implement simple registers and latches.
- contingencies 4y agoYes, TTL is a good description (from Wikipedia). The title less so.
