The games for these systems, along with the demo scene were able to achieve high sophistication and technical polish using only simple, blocky graphics and digitally generated sound.
Later the Atari ST series and Apple Macintosh II extended the concept; the Atari integrated a MIDI port and was the first computer under US$1000 to have 1 megabyte of RAM which is a realistic minimum for multimedia content and the Macintosh was the first computer able to display true photorealistic graphics as well as integrating a CD-ROM drive, whose high capacity was essential for delivering multimedia content in the pre-Internet era.
The original PCs were devised as "serious" business machines and colorful graphics and powerful sound abilities weren't a priority.
The few games available suffered from slow video hardware, PC speaker sound and limited color palette when compared to its contemporaries.
They have dual or more core CPUs clocked at 2.0 GHz or faster, at least 4 GB of RAM and an integrated graphics processing unit.
