YES, a modern version of the 74181 is equivalent to about 12-20 chips in the LS or HC series. It would be so useful. Someone should do a tiny tapeout!

Dread was the desired outcome haha. I was also kind of excited to prove to others that you can have fast clock speeds without spending forever bending and stripping wires (for my fellow lazy/busy people).

Honestly even though it is a bit of a rats nest, in my mind it feels like a kind of organized chaos. And easy to trace any single route.

For the microcode ROMs they can just be “hardwired” with a zillion simpler gates. This has the added benefit of supporting way higher clock speed. For my planned program ROM you would either have to input manually like the first computers, or use other things like punch cards or your computer would be again “hardwired” to load programs from some other media

You can do so much before needing to buy anything or even learn any electronics. There’s a lot of good simulation options out there like Digital, Logisim-Evolution, even video games like Turing Complete and Logic World! That’s before you even get into stuff like Verilog. Thanks for the kind words!

Check the reviews online, but generally random bits of Go code are presented with no build-up or explanation. B Trees are implemented immediately and without explanation. The book is incredibly short and seems just like a loose collection of notes, rather than an actual book. Very interested to check out the new version
