Acorn Archimedes A410/1

The Acorn Archimedes A410/1 revised the professional A400 range with updated memory control, RISC OS and a 1MB entry configuration. Its larger case retained four podule slots and room for internal storage.

The /1 range marked the point at which RISC OS replaced Arthur as the standard Acorn desktop environment.

Notable Features

• Acorn ARM2 at 8 MHz provides the system’s processing architecture.
• The standard memory configuration was 1MB; expandable to 4MB.
• Storage was supplied as 800KB 3.5-inch floppy drive; hard disc optional.

Historical Significance

• The /1 range marked the point at which RISC OS replaced Arthur as the standard Acorn desktop environment.
• 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.
