Upgrading an ARM3 A3010 with RISC OS 3.11

After completion of the ARM3 and IDE upgrades, the final upgrade to the ARM3 A3010 was the fitting of RISC OS 3.11. Andrew sent me a set of RISC OS 3.11 ROMs to replace the factory fitted 3.10 ROMs and the photo set below details what's involved.

This meant a final strip down of the machine in order to get to the ROM sockets.
