I wrote a custom network stack in C to run on my custom silicon RISC-V core, supporting both IPv4 and IPv6 and its now good enough to make HTTP requests. But maybe I'll turn that around and have it accept HTTP requests. We'll see.

I really want
@mith.ro 's wafer.space silicon manufacturing shuttles to succeed and continue to be available, so I was trying to brainstorm some retro-computer/console chips which may be viable.
Most can be done on FPGA today, but custom silicon could make assembly cheaper (reducing FPGA support).

It was the first time we enabled 4 tile high designs, enabling a monster crowd sourced RISC-V microcontroller competition called Asteroid. At 60k standard cells, this is the biggest design so far on Tiny Tapeout.

Inspired by Peter Kinget, we commissioned Andrew Kang to create a Mini MOSBius especially for us. The idea is to enable analog designers to get faster feedback on their circuit designs with an analog FPGA.

Well, it blinks.
The whole you have to unplug it from your computer and plug it into an SD card slot that doesn’t act as an SD host to run the design thing may get old rather quickly.
