So... at what point does someone re-create a 386 or 6501 but using only a motherboard, with no discrete circuits?

If you haven't clicked the link .. that is one thick circuit board. They didn't give a dimension, but it looks to be at least 1cm.

Can someone explain the implications of this?

Wouldn't this just be a mess signal integrity wise?

Yo dawg, I heard you liked layers inside your layers.

TOKYO, April 25, 2025 -- OKI Circuit Technology... OTC is seeking to establish mass production technology by October 2025 at its Joetsu Plant in Joetsu City, Niigata Prefecture
Dan, this is 2025! Not a Hacker News-worthy at the end of 2026.
Also, 124 layer PCB is ONLY 15% extra than the conventional 108 layer PCB. Incremental upgrade!
