- WHAT:
- =======
-
- This is a text descriping how to connect a PC power supply to an A1200 (or
- A500 or A600).
-
- WHY:
- ======
-
- Because an Amiga PSU is so incredibbly overpriced.
-
- HOW:
- ======
-
- The Amiga uses +5v, +12v and -12v. The pins are located like this from the
- PSU:
-
- ----OOO----
- | |
- (Brown) +12v -> | X X | <- Signal GND (Black)
- | X |
- Not Used ??? -> | X X | <- +5v (Red)
- | ^ |
- -----|-----
- |
- -12v (White)
-
- To be sure of the colors, try testing it with a multi-meter, or in the lack
- of better, you can use a small lightbulp (like in a bicycle lamp), and a
- battery. Connect the bulp to one end of the battery, then put the lamp to one
- of the pins from the socket from the 'Amiga PSU power wire', make sure the
- lamp only touches one pin, then touch the other end of the battery with the
- (de-insulated) wires from the 'Amiga PSU power wire' one at a time. When the
- light bulp lights, you have obviously found the correct wire. If this doesn't
- make sence, perhaps im too stoned or you should just have a nice game of
- Pacman.
-
- On the PC-PSU, there should be two 6-pin sockets. The pinouts are
-
- 1st socket:
- Pin 1: GND (Black)
- Pin 2: GND (Black)
- Pin 3: -5v (White)
- Pin 4: +5v (Red)
- Pin 5: +5v (Red)
- Pin 6: +5v (Red)
-
- 2nd socket:
- Pin 1: Who cares ???
- Pin 2: Does anyone care.
- Pin 3: +12v (Yello)
- Pin 4: -12v (Blue)
- Pin 5: GND (Black)
- Pin 6: GND (Black)
-
- The idea is to connect the +5v, +12v, -12v and GND signals from the PC-PSU,
- with the +5v, +12v, -12v and GND.
-
- Heres a connection table:
-
- PC Wires Amiga Wires
- -----------------------
- Black -> Black
- Yellow -> Brown
- Blue -> White
- Red -> Red
-
-
- Figure the rest out for yourself; use your imagination; if you haven't got one,
- go sit in a corner.

- WHO:
- ======
-
- The Hanged Man
-
- WHEN:
- =======
-
- 6 o'clock in the morning (night ?) one saturday in april 1996.
-
- HELP:
- =======
-
- Well, it worked for me.
-
- P.S.:
- =======
-
- Try this hack at your own risk. It can be very dangerous. You may even die,
- imagine that.
-
- P.P.S.:
- =========
-
- I would like to thank Jens Hansen from Stenløse, Denmark. Without whom i had
- stopped when i blew up my A1200 with static electricity. Allways remember to
- completely disconnect any periphals and equalize your voltage with the computer
- by touching the shielding of the computer before working with it. NEWER use a
- radiator or waterpipes to 'discharge' as you will become differently charged
- than the computer, wich causes current to flow, and blow up my computer :(
-
- P.P.P.S.:
- ===========
-
- If you are using an A1200 and 3.5" internal HD, let me suggest that you make
- an additional power socket by soldering one to the inside of your computer (see
- picture).
- There is two advantages to this approach:
- 1. By using the extra power socket for the HD, the power will run directly from
- the power input to the HD. If you are powering your (3.5") HD from your floppy
- power, the power used for the harddisk, wich is quite a lot, will run through
- your motherboard and eventually disturp some components, making your computer
- unstable; especially when using floppy and HD at the same time. The extra power
- cable will make your A1200 with 3.5" HD more stable. Especially if you have a HD
- that uses a lot of power.
- 2. By partially isolating the powerconsumption of the HD from the motherboard,
- you might reduce the risk of damaging the motherboard by connecting a faulty HD.
-
- P.P.P.P.S.:

-
- No, i'm not utterly insane. If you have any questions whatsoever, feel free to
- mail me (see .readme). For those of you Amigans without email: You're really
- missing out on something. If you can afford it, you should do so ! It's here !!!
-
- P.P.P.P.P.S.:

-
- Remember, this is just guidelines !!!! I haven't been particular thorough on
- the data, so double check me ;)
