Acorn Risc PC 600

The Acorn Risc PC 600 introduced a modular slice case, replaceable processor card, VIDC20 video and a second processor slot. Its 30 MHz ARM610 and SIMM memory represented the first major Acorn desktop redesign since the original Archimedes.

The Risc PC architecture allowed ARM, x86 and later StrongARM processors to share one system, and became Acorn’s principal professional platform.

Notable Features

• Acorn ARM610 at 30 MHz; later 33 MHz provides the system’s processing architecture.
• The standard memory configuration was 2MB to 8MB standard; expandable to 256MB.
• Storage was supplied as 1.6MB floppy drive and IDE hard disc; optional CD-ROM.

Historical Significance

• The Risc PC architecture allowed ARM, x86 and later StrongARM processors to share one system, and became Acorn’s principal professional platform.
• This record separates a genuine processor, memory, enclosure or storage model from software bundles and dealer-only configurations.

Collector’s Notes

• Confirm the exact model from its front badge and rear serial label because many Acorn systems were upgraded during their working lives.
• Original monitors, three-button mice, keyboards, expansion podules, manuals and installation media add historical value.
