Migration of PDP-11 Systems
Starting from the existing PDP-11 application software, there are basically two approaches to re-use these applications on a new platform:
Source code migration
This is the 'traditional' method of porting, starting from the original PDP-11 application source code, adapting and recompiling it for a new platform.
Modern operating systems are quite different from those that were designed for the PDP-11 man decades ago. This usually means an extensive redesign of the application there where operating system services are used. Obviously, the application source code has to be available to modify it.
PDP-11 hardware virtualization
An alternative to porting is to execute the original PDP-11 binary code on a modern platform without modifications. This can be done with our product CHARON-TB.
Whatever the type of migration, PDP-11 applications have been successfully transplanted by Software Resources International to UNIX, Linux, VMS, Windows NT and other platforms. Both solutions offer a much lower cost and require less time than completely rewriting the application.
