Both StrongARM Risc PCs that Chris Whytehead examined have the issue 3 main board, part 1208,000, with 16-bit sound, the IOMD21 memory controller and VIDC20, and processor card part 1111,150 issue 3. The front processor connector carries the StrongARM card and the rear one takes an optional x86 PC card. The supply is rated 103&nbsp;W.<ref name="chrissa" />
