Theoretical computer by M. Morris Mano

The Mano machine is a computer theoretically described by M. Morris Mano. It contains a central processing unit, random access memory, and an input-output bus.

Its limited instruction set and small address space limit it to use as a microcontroller, but it can easily be expanded to have a 32-bit accumulator register, and 28-bit addressing using a hardware description language like Verilog or VHDL; and at the same time, make room for new instructions.

Characteristics

The Mano machine is similar in many respects to the PDP-8, such as the same address space, only one accumulator register, and many similar instructions.

The Mano machine has a 4096x16 shared data/program memory segment requiring a 12-bit address bus. The data bus is 16 bits. There are 8-bit input/output buses for external communication, and associated interrupt flags.

There is one 16-bit accumulator register, and single-bit registers (latches) for addition
