John Doran’s D16 Homebrew Computer

July 7, 2011 | Homebrew CPU | By: Mark VandeWettering

Just another link to inspire me in my glacial moves toward designing a CPU of my own:

The D16/M is a general-purpose, stored-program, single-address, 16-bit digital computer using two’s complement arithmetic. It manages subroutine calls and interrupts using a memory stack. The processor may directly address 64K words of memory or I/O. Its timing and control unit is microprogrammed (fully horizontal, with a 72-bit control word).
