KOJRO Retro innovations | It’s only logical. Episode 21 “We latch on to yet another Chip” A Christmas Calendar from KOJRO RI. @kojroRI | Uploaded December 2023 | Updated October 2024, 1 hour 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.
In episode twenty one we look into latches, and also broaches into 3 state, we are also able to get something to work on the Breadboard.
