PDP-11/70 Machine Configurations

PDPjs supports a variety of PDP-11/70 machine configurations, including:

The PDP-11/70 with Front Panel also comes in a Debugger Configuration, which features a section on "Toggle-Ins" for your switch-toggling enjoyment.

Unless otherwise specified, the above configurations include 256Kb of RAM. The PDP-11/70's 22-bit architecture supports a maximum of 3,840Kb of RAM, since the last 256Kb is reserved for UNIBUS devices. The top 8Kb is known as the I/O Page, a region containing hardware registers belonging to the CPU, MMU, and assorted peripherals.
