Apple //c from 1984 (with the original receipt!) The composite video output means I can plug it right into my 50" tv without any special hardware and everything looks great.
I removed the disk drive cable from the motherboard and plugged a floppy EMU in, and now my kids play Lemonade Stand, Dig Dug, Oregon Trail, Carmen San Diego, and dozens of other classic games. https://www.bigmessowires.com/floppy-emu/
