TowerHawk 1200ex power connections

[Kitch]

I've just picked up a TowerHawk 1200. It's missing its ATX power supply among other things. I was looking at powering it up to see if the A1200 mother board inside still works.
It looks like the ATX power supply must plug into the KeyOn PCB just above the mother board. There are two 6pin plugs that look just like ones I have seen coming out of an ATX power supply I have inside an old 486. The third plug on the PCB looks like it has 20 pins (two rows of ten)and I have know idea what that one is for?
Any help would be much appreciated.

Thanks, Andrew

Hi !

I think the manuals for RBMs Towerhawk and Onboard (ZorroII-expansion) are available on RBMs site
http://www.rbm.de .The site might contain some German,but the manuals atleast were there,at some point,
in English also.The power supply indeed plugs into the Keyboard interface and it plugs to the A1200 via
a small adaptor from the outside of the tower. The 20 pin plug is the one coming from the ATX supply -
I don't know the 'pinouts' of it or whether it's a standard or made specifically for this tower (no
experience in power supplys..). The two 6-pin plugs,labelled P8 and P9 respectively,come from the
OnBoard ZII-addon.Also,On the interface there's the obvious keyboard flexcabel connector and on it's
left side the towers LED connectors and the leftmost connector is for the A1200 LEDs.

Unfortunately,you won't find the 'pinouts' of the power supply 20-pin plug from the manuals and unfortu-
nately I'm too lazy to open it up (and probably I wouldn't be able to help anyway,since I don't
have the expertise).

I checked the colours of the leads on the power connector.The connector is plastic and has a
plastic clip for a more tight connection.Probably available from any good computer part - stockist.

The colour 'scheme' from LEFT TO RIGHT and the UPPER row first is :

Red-Red-White-Black-Black-Black-Green-Black-Blue-Orange

LOWER row (from LEFT TO RIGHT) :

Yellow-Violet-Gray-Black-Red-Black-Red-Black-Orange-Orange


I doublechecked them,but accept no liability if I'm colour blind.Hopefully U've already got this
information elsewhere as your post was a few months old.

P.S.So the Yellow is beneath the Red and Orange leads at the right end of each row.

Regards,

Kenneth

you really need the keyboard pcb, as the psu connects there, and from there the amiga motherboard... I can post detailed pictures if nescessary...
