Scandy - Scandoubler A1200 internal
Operating Instructions
Thank you for purchasing the MicroniK internal Scandoubler, which is suitable for all A1200
motherboards.
The Scandoubler doubles the 15.6 kHz to 31 kHz so that you are able to display PAL HighRes on a
VGA-monitor. You can therefore display all of the Amiga display modes at a suitable multisync
VGA-Monitor. For the "Super 72" mode you will need a monitor with a horizontal scan rate of at
least 24 kHz and the for the mode "A2024" you will need a special monitor. For further information
please refer to your Amiga manual.
Before start, disconnect your computer PSU and all external cable connections such as the monitor,
mouse, modem, printer and so on. Please ensure that you have a clear workspace and enough room
for the installation.
If you have a infinitiv Tower:
Open the infinitiv tower according to you manual. Disconnect all cables (remember the polarity of
the cable), add-on cards and slide out the mainboard carrier-frame. Move the mainboard carrier-
frame with the Zorro board (if there is one attached) to your work desk and disconnect it from the
maninboard.
If you have a desktop A1200:
Caution: Before open your A1200 you should know that this operation means the loss of
warranty.
Put the A1200 upside-down with the keyboard pointing to the bottom, so that you can see the air
vents. Unscrew the 8 screws with a philips crew-driver, taking note of the location: 3 screws
(remember the location) close to the air vents (the screw in the middle i covered by the warranty
seal, which will have to be removed first) and 5 remaining screws on the case bottom. Now carefully
turn over the A1200 so that the space bar points towards you. You can fold back the top of the case.
Please pay attention to the cables that lead from the mainboard to the LED board on top of the case.
Removal of the Keyboard, Floppy and Hard disk drive:
You can see a thin green transparent foil cable, which leads from the mainboard to the keyboard.
This foil cable is fixed with a white plastic clip. To take out the foil cable the holding mechanism
has to be loosened as follows: Carefully raise the clip with a small flat screw-driver on both sides,
until you can easily pull out the green foil cable.
Now unplug the power cable and the short grey data cable (remember the polarity) from the floppy
drive. The floppy drive is fixed with a screw and a metal square. Remove the screw so that you can
easily remove the floppy drive. Finally, unplug the LED-, Power- and the floppy data cable from the
mainboard (remember the polarity).
