Atari commissioned NMB to make many keyboard for the PC lineup over the lifespan of the computer series Atari PC. Atari introduced the PC series in 1987. The original PC1 was introduced using the original Atari ST case with a single floppy drive. The price for the PC1 was right in line with the market and these computers were popular in the EU and UK regions.
Shortly after the PC1 was launched and customers didn't like the single drive as the overall size with an external drive as well the PC2 was launched. The PC3 which was launched after the PC2 is the last Atari PC that will come with a NMB keyboard.
