Castle 101 Quad Gate

Castle 101 packs four independent gates in one module for high-density Boolean work: combining counters, shifts, and clocks into gating and synchronous masks without consuming multiple 4 HP slots with single-gate breakouts.

Role in a patch

After 000 / 001 conversion and 010 / 011 timing, use 101 to recombine and inhibit conditions before the matrix and output path. Use consistent ground and return to keep crosstalk low when toggling at video-related rates.

Power and build

Castle 5V / -5V (and per-revision +12V where required) only; verify BOM match to your silkscreen revision.
