The 500 Series was introduced in 1982 with the 9020. The 9020 was HP's first commercial 32-bit desktop computer (the company had abandoned its 32-bit "Omega" prototype computer a dozen years earlier). It was also the first RISC computer made by HP, based on the FOCUS chip (before the advent of the Spectrum PA-RISC CPUs), running at 18 MHz. The 500 Series computers were also the first HP computers to run HP-UX.
