ARM3 processor, soldered to an A5000 motherboard. A pin half way up the side closest the camera has been repaired by carving out part of the IC package with a diamond grinder and attaching a hair-thin wire.

This isn't a repair one should consider doing lightly. But sometimes there's no alternative. #retrocomputing #electronics #acornarchimedes #AcornComputers

A history of ARM, part 1: Building the first chip In 1983, Acorn Computers needed a CPU. So 10 people built one.

Without an ARM, there'd be no RISC OS! Modular, compact and quick. #Retro #AcornComputers #OpenSource #RISCOS #London #Show #October

Acorn's legacy extends beyond the BBC Micro; their CPU design expertise led to ARM's success. This lineage underpins the vast majority of modern mobile devices, a testament to their foresight. #AcornComputers 4/6
