It has been working for 40+ years, it does the job, everybody using the system is familiar with it, it's robust (no network required), it's exceptionally easy to service and maintain (all through-hole technology on a single, comfortably large board), and the entire unit (computer, monitor, cassette drive) is rated at just 45 W (so it's probably using less than that.) Also, it's a beautiful machine adding a bit of joy to the work life. – Why should you want to change this?
