Commander X16 Emulator
The Commander X16 is The 8-Bit Guy’s dream computer, designed to evoke the same fondness and nostalgia many of us had for 8-Bit computers, while retaining closeness to the hardware from a programming perspective, unlike the Raspberry Pi and others. But more than that, it is intended not only as an educational tool but to solve some of the issues of finding an 8-Bit system to tinker with today; namely ever-increasing costs, auction site price gouging/sniping, lack of replacement parts, and unreliability of 30-year old hardware.
