Hey @chrisgammell.bsky.social , I've just caught up on your excellent chat with Tim Ansell @mith.ro in The Amp Hour ep #703.
Have you scheduled and executed the 2 hours on the weekend to start your own chip-making journey yet?
A remake of the much loved and rare 6580/6581 SID chip perhaps?

**Interesting SPI Routing with iCE40 FPGAs**
I wrote about iCE40 FPGAs, and why the way an FPGA is configured can lead to interesting board design decisions. @mith.ro's Fomu is a useful study due to eschewing a USB-Serial chip for accessing the FPGA and SPI flash.

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).

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.
