- emeraldd 4y agoThose are fun little chips if you need a small audio power amp. Had the same thought when I pulled up the article.
- Starwatcher2001 4y agoNot what I expected, but that brought back memories. The LM380 (the 386's cousin) was the first analog chip I ever used, somewhere around 1976. I built a small headphone amp with the chip and a handful of discrete components on a piece of Vero board. I think the circuit came from the chip's implementation notes in the old RS Catalog.

- pengaru 4y agoThe i386 had 100x the number of transistors, it'd cover an entire wall.
- duskwuff 4y agoThat just sounds like a challenge. :)
- coupdejarnac 4y agoI found this tool for converting HDL to PCB layout with discrete logic. It should make the dream of a wall sized computer much easier lol. https://hackaday.com/2021/11/13/using-vhdl-to-generate-discrete-logic-pcb-designs/ https://hackaday.com/2021/11/13/using-vhdl-to-generate-discr...

- userbinator 4y agoIndeed, that's what I was expecting too. The 80386 is largely microcode-driven so I thought someone had managed to condense the datapath and sequencer enough to make it implementable with discrete components.
- bitwize 4y agoAww man. Was hoping we could rebuild Strong Bad's old computer.
