 Acorn ARM610 CPU prototype (front)

 Prototype ARM610 CPU card with GPS P611ARMPR CPU clocked at 30MHz. The "ISS. C" shows it is a prototype (or pre-production) because Acorn used issue letters for development hardware and issue numbers for production hardware.

The 30MHz ARM610 CPU is the standard CPU card in the Risc PC 600. The later models (ACB6nn), which were launched at the same time as the Risc PC 700, had a 33MHz ARM610 CPU. The ARM610 was made by GEC Plessey Semiconduction (GPS), one of ARM's many licencees.
