I have just released the Gerbers for the PICO9918 PCB v0.3. I've been running tests continuously for a week or so on this revision and it is working great.

I've been thinking about how to go about getting this tested on more machines as I've only tested on two TI-99/4A's (PAL and NTSC) and my HBC-56. I might produce a few of these to send out to those who are willing and able to try it on a wider range of machines. Let me know if you're interested in this.

Note: This PCB revision is not representative of the final release which will be a single board without the need to the piggy-backed Pi Pico board. However, v0.3 is fully functional. If you're a tinkerer or early-adopter type, go ahead and give it a go. If not, I suggest waiting.
