KOJRO Retro innovations | It’s only logical. Episode 12 “We look at the world through the Oscilloscope”. A X-mas Calendar. @kojroRI | Uploaded December 2023 | Updated October 2024, 10 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 twelfth episode will also be about making a working flip-flop but this time we first have to make sense of my new oscilloscope, the ZEEWEII DSO2512G
