The 32016 second processor is also present as part of the "Acorn Cambridge Workstation" using an 8 MHz CPU and 4 MB of RAM, sold as part of the Acorn Business Computer line. Originally, Acorn had apparently sought to use CPUs rated for 10 MHz, but seemed to have settled for available parts as the different products were introduced. The second processor board was also able to use 64-kilobit or 256-kilobit RAM devices, thus allowing the earlier 256 KB specification to be upgraded to 1 MB as the higher-density devices became available and affordable.
