I am in the process of restoring a IBM System/36 Model 5363 and need to locate a copy of System Support Program (SSP v5.1) to complete the effort and get the machine up and running. I am having a difficult time locating this software. This is for a non-production, non-comercial effort to serve as an exhibit on how data processing has changed over the decades. I am hoping someone in this forum can point me in the right direction of a source for this important piece of software. Any assistance would be greatly appreciated.
