JLCPCB have neither the TPF133A nor the THS7316 3-channel 36 MHz video amplifiers. They do have the [MS1681/](https://jlcpcb.com/partdetail/Hangzhou_RuimengTech-MS1681/C231920), which is a single-channel 36 MHz 6dB amplifier, in a SOT-23-6. We'd...
TI withdrew the TLV320AIC23B, marking it obsolete. This means [JLCPCB](https://jlcpcb.com/parts/componentSearch?searchTxt=TLV320AIC23) no longer stock it. Specifications included: * TSSOP package, so you can see the pins and hand-solder it * Stereo...
Calculates useful semantic versions and handles tags and PRs and branches.
Apparently Class 2 (e.g X5R) MLCCs aren't good for audio. We should use Tantalum or Class 1 MLCCs. https://youtu.be/kUruN6WBgSw
Perhaps a useful future feature would be support for WASM-4 "carts"? https://wasm4.org/docs/ It targets retrogaming and can be run in small devices as well as online. - 4 color 160x160...
There were many office PCs in the BTX and microBTX form factors, that have their motherboards failed since. As BTX has the layout reversed, it is incompatible with ATX layout...

Olimex have an [ICE40HX8K FPGA board](https://www.olimex.com/Products/FPGA/iCE40/iCE40HX8K-EVB/open-source-hardware). This has a 34-bit GPIO header. It should be possible to wire that header to the 26 data pins on the Neotron Pico's CPU...
