Prime Candidate

My unit is over 35+ years old, and it still runs flawlessly. It is one of the most indestructible pieces of gear I've ever owned. The CPU is programmed to prioritize the MIDI signal over everything, making it more precise (less latency) than any modern computer. It is THE best and most reliable computer/notator/sequencer I've ever own. Obviously, you have to deal with floppy disks (one of the least reliable media available), but if you understand the risk and prevent it by making several copies of your saves, you are more than fine!
