- Incorrect. ARM710 is Architecture 3. All Thumb cores are Architecture 4.
- This does include the ARM7T. There do not exist any processors which
- support both Thumb and 26-bit modes, therefore the ARM710 which runs
- RISC OS in 26-bit mode does not have Thumb. ARM8, ARM9 and StrongARM
- cores are all Architecture 4.
