It’s an obsession, really — using discrete logic chips to scratch-build ... crystal oscillator clock with a simple 1 Hz 555 timer circuit; the reduced clock speed made it easier to check ...

We often think of analog computing as a relic of the past, room-sized monstrosities filled with vacuum tubes doing their best ...

Glue logic was widely used in the past when fewer circuits were placed on the same chip. THIS DEFINITION IS FOR PERSONAL USE ONLY. All other reproduction requires permission.
