An 8-bit processor, with 16-bit addressing, but which could
only access 32K of memory (1-bit for indirection). The
Ferranti F100-L was designed by a British company for the
British Military.
The unique feature of the F100-L was that it had a complete
control bus available for a
coprocessor. Any instruction
the F100-L couldn't decode was sent directly to the
coprocessor for processing. Applications for coprocessors at
the time were limited, but the design is still used in modern
series.
