PDP-11/45 Machine Configurations

PDPjs supports a variety of PDP-11/45 machine configurations, including:

All of the above configurations include 248Kb of RAM -- the maximum supported by the PDP-11/45 architecture. The top 8Kb of the PDP-11/45's 18-bit address space is occupied by the I/O Page, a region reserved for hardware registers belonging to the CPU, MMU, and assorted peripherals.
