Jeff Parsons 22728fb7e9 v1.37.1: Fixed a CPU bug wherein resetting a running CPU could result in multiple runCPU() timeout handlers being created (there should never be more than one outstanding runCPU() setTimeout request); also modified the Keyboard component to use a CPU-driven timer instead of setTimeout() for keystroke injection, so that stopping/starting the CPU won't interfere with the injection process

array Changed the default page "exit" event handler from "onunload" to "pagehide" for iOS; hopefully, auto-resume machines will work better on mobile devices with that change 2017-06-25 08:32:27 -07:00

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.
