How do you express those as a truth table? My outline of lessons is: 1. Boolean logic expressed with electronics, specfically TTL gates and wires. We'll hook up switches and LEDs and see the logic happen. 2. Repeat the experiments of (1) with an FPGA substituting for the TTL gates. Needs a computer (laptop) running yosys and nextpnr-ice40. Debian Trixie is known good, and a recent Ubuntu should also be easy. If you prefer something else, LMK and I can work with you ahead of time to get the toolchain installed. I'll supply the $50 pico2-ice FPGA board. 3. Synthesize and run clocked logic to create sounds; based on the fpga4fun MusicBox lesson at https://www.fpga4fun.com/MusicBox.html . - Larry
