Procyon B // Commodore

In 1954, Commodore Business Machines was started as a typewriter company, before pivoting to personal computers in 1977 with the PET 2001, just in time for the "1977 trinity" of Apple II, PET 2001, TRS-80. Commodore would go on to make many more advancements in computing until its bankruptcy in 1994.

This web page uses a screenshot of OpenMPT running on my Linux laptop through WINE, though this is not best practice and I actually use such software on Windows. OpenMPT is a tracker, and, as such, is descended from The Ultimate Soundtracker for the Commodore Amiga, itself a sample-based adaptation of Soundmonitor for the Commodore 64. This is because both machines were ahead of their time in sound, compared to contemporaries such as the Sinclair ZX Spectrum, which had just a 1 bit beeper.
