An early ARM3 upgrade for the Archimedes range. In its review of this upgrade Risc User magazine estimated that it was between 2.5 and 5 times faster than an ARM2 CPU and posed the question ARM3 or Floating Point Co-processor, it is unnecessary to add that users went ARM3 and very few Floating Point Co-processors (which only worked with the ARM2) were sold in comparision.
