PDP8/a Initial Power Up

Hello everyone - my first post, so be easy on me! I have just acquired a PDP8/a and a Remex punch tape reader. The unit starts up and displays some data on the displays, and that is about all I can tell you. I am going to do some googling about this, but I am looking for basic initial tests .... something I can enter via the keypad. I learnt some basic programming in 1978 on a PDP8, but that was the last time I touched one, so if you are going to suggest some tests, I need complete instructions. I don't know how to modify a memory location, let alone enter and check a program. I will pick all this back up very quickly and I do use computers in my work a lot - I am also an electronic hobby guy and have been for years. My point is I am OK with component level measurements, I have a scope and probes, etc. So there you go - hope to hear back form you guys.
