AWhat changed
A low-complexity 32-bit processor became practical in the Acorn setting.
Scientific scope
1985 ARM1 design by Wilson and Furber; physical layout, companion chips, later ISA versions and ecosystem excluded.
Evidence
The linked sources identify this contribution and its scope. WRS has not independently reconstructed the scientific claims. The record is the 1985 ARM1 processor design attributed to Sophie Wilson and Steve Furber. Acorn management, VLSI physical implementation, companion chips, later ARM versions and the wider commercial architecture family retain separate attribution.
