Hi!

I've just got an Apple Motherboard without power-supply and keyboard.

The Motherboard is organized like this:
+-----------------------------------------------------------------+

|                                                                 |
|  Port 7                                                         |
|  Port 6             many many IC's                              |
|  Port 5   6    Z    ...               Keyboard-DIL -> cable -> SUB-D 9
|  Port 3   5    8                                                |

|  Port 1   2    A                                                |

|                                                                 |
|   Power-connector                                               |

Maybe you can tell me a few things:

 1.) What type of Apple II is this? (it has both, Z80&6502)
     Apple IIe  IIc  IIgs ... ??? (i know nearly nothing about AppleII)
 2.) What Power-Supply do i need
     (The connector says:  GND 5V 12V +5V +12V, two questions:
      a) how many Amperes for each Voltage ?
      b) What does 12V and 5V mean?   +5V and +12V  or  -5V and -12V ????
 3.) Where can i get a Keyboard??? Does a PC-Keyboard work???
     I think, the SUB-D-9-pin connector has 8 Pins connected ...
     How does this Keyboard work? Has anyone Schematics of it????

Thank you
