Very cool. Makes me wonder if I could/should make a little 555 timer reset circuit for mine? |

Yeah, especially if you're connecting it to a CRT as there is never an invalid VGA signal in this case. Well, I have not confirmed that, if there is, it only exists for under 200ms as power comes up. |

I am planning on hooking it up to a CRT at some point soon - I have a few AD724 chips which can take the VGA signal and convert it to NTSC composite. I can't help but wonder if I can somehow fudge the graphics a bit to trick NTSC into displaying color 🤔 |

Very nice idea. A 555 timer would be a valuable addition. The reset on the Minimal is -- well minimal :-) |

I had one of these kicking around (it was from a washing machine :P ). It is a reset circuit with a watchdog, not using that, just the reset. Is a really nice addition to have that as now I can connect the USB and source it for power and it just starts up nicely. The manual reset button still works fine.
