ohio scientific haul

Hello! Yesterday I brought home a pile of OSI equipment. I got a Challenger II (in the blue, rectangular case,) a Challenger 4P case with keyboard (seems to connect to the main box as a keyboard,) two 5.25" disk drives in the style of the 4P and two joysticks. Inside the challenger are the following boards: 505 Rev B CPU/IO/Floppy 527 24k RAM 540 Rev B Video 567 Votrax Speech Synthesizer w/ external module; The Challenger II seems to have a well modified power supply, including and an added circuit board with two transformers, as well as four volt meters, mounted in cardboard and taped to the inside of the case. My first question in what is likely to be a long series is: If I intend to try and get it running, what is my first step? I'm not entirely sure what I'm going to do with the system yet. Its the first time I've had something of this caliber. I have no idea what its worth Thanks Joe -- Joseph Giliberti Jackson, New Jersey Come Visit the InfoAge Science History Learning Center and Museum Get more information at http://www.infoage.org
