https://en.wikipedia.org/wiki/HP_9000 :
> The HP 9000 brand was introduced in 1984 to encompass several existing
> technical workstation models previously launched in the early 1980s. […]
> The Series 500s were based on the HP FOCUS microprocessor. […] The 520 was
> a complete workstation with built-in keyboard, display, 5.25-inch floppy
> disk, and optional thermal printer and 5 MB hard disk. […] The processors
> in the original Series 500s ran at 20 MHz, and could reach a benchmark
> speed of 1 MIPS.
https://en.wikipedia.org/wiki/HP_FOCUS :
> The Hewlett-Packard FOCUS microprocessor, launched in 1982, was the
> first commercial, single chip, fully 32-bit microprocessor available on
> the market. […] The FOCUS […] was a stack architecture, with over 220
> instructions (some 32 bits wide, some 16 bits wide), a segmented memory
> model, and no general purpose programmer-visible registers.
