some to be the BBC Model C expected from Acorn, raising questions about the work that had been done to the BBC Model B hardware and whether such a board, designed for a reduction in chip count and production cost, would eventually see use in the conventional BBC Micro range, bringing lower pricing and higher reliability.

Colour monitor Announced price (as Acorn Cambridge Workstation): £5845 for 1 MB model with RAM upgrades at £1000 per megabyte The reason given for providing Panos as the operating system at the launch of the Acorn Cambridge Workstation instead of Xenix, despite Acorn having contracted Logica to port Xenix to the machine, was the apparent lack of a working memory management unit (MMU) in the National Semiconductor 32016 chipset, for which a socket was provided on the machine's processor board. Thus, the machine was delivered with only the 32016 CPU, 32081 FPU (Floating
