KOJRO Retro innovations | It’s only logical. Episode 5 “The NOR gate”. A Christmas Calendar from KOJRO Retro Innovations. @kojroRI | Uploaded December 2023 | Updated October 2024, 2 hours ago.
This is my second take on a 24 episode Christmas calendar. Last time the task was presenting a new vintage computer from the MS-Dos area each time. This time I am going to cover some even older bits of computer history, and these bits play a part even today. We are going to look into the bread-and-butter logic chips, and the theory behind them. Mainly the 74xxx series of TTL gates.
The fifth episode will be about the NOR gate.
