PDP-11/70 Machine Configurations
|
|
--------------------------------
|
|
|
|
PDPjs supports a variety of PDP-11/70 machine configurations, including:
|
|
|
|
* [PDP-11/70 Boot Monitor](/devices/pdp11/machine/1170/monitor/) (with [Debugger](/devices/pdp11/machine/1170/monitor/debugger/))
|
|
* [PDP-11/70 with Front Panel](/devices/pdp11/machine/1170/panel/) (with [Debugger](/devices/pdp11/machine/1170/panel/debugger/))
|
|
* [PDP-11/70 "Server Array"](/devices/pdp11/machine/1170/array/)
|
|
* [PDP-11/70 with VT100 Terminal](/devices/pdp11/machine/1170/vt100/) (with [Debugger](/devices/pdp11/machine/1170/vt100/debugger/))
|
|
|
|
The [PDP-11/70 with Front Panel and Debugger](/devices/pdp11/machine/1170/panel/debugger/) also features a section
|
|
on "[Toggle-Ins](/devices/pdp11/machine/1170/panel/debugger/#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.
