Apple TechStep

The information you asked for is as follows: output DC 9V 500mA Class 2
power supply (but you can run it off a 9 volt battery, you do not need the
ac adapter), part number 077-0668, outer tip is positive and inner tip is
negative. The manual is 70 pages long and if you need more info let me know.
The system is pretty simple to operate once you get all the cables and
software for it. There are four test modules with module four being the
hardest to get. Here's are little more tips on it: powered by a MC68HC11
8-bit single-chip microcontroller; there about 4 diskettes that come with it
(with the report generator diskette being the most important); cables that
come with it are: ADB(2), mini DIN-8 serial(2), DB-25-to-25 SCSI(1), and
stereo audio(1). Hope this helps. John
