Yep, but it has changed quite a bit since then. 30 years ago there was only console mode, albeit in different flavors (unix/DOS). Nowadays the main product is Windows oriented and also has a Web offering. You can still buy a console mode linux version, but it hasn't had updates in over a decade. Yes it runs and works on recent Linux versions, no I would not recommend spending any money on that. Your 30 years old data files however could still be read. You might need to migrate it to a newer format if you want to extend and change things, but it would still work.
