Title: Rare 1200 mobo (misses one mouse/game port)? Also male IDC10...
Post by: Jose on May 06, 2007, 02:15:54 AM
Got a spare A1200 mobo that I'm willing to sell but the thing misses one of the mouse/game ports and has an IDC10 female connector instead. It's also a smaller motherboard, missing the area beneath where the missing rightmost gameport/mouse would be.
How frequent are these ?

Anyways, problem is that the port is on a flat cable (IDC10) wich also has a female connector. Electronics stores allways have female IDC connectors , couldn't find any male thing on both sides. Any hints ?

There's nothing missing (well the flatcable with connectors is =), your motherboard probably is a revision 1D4 board. Check out the pictures on BBoAH (http://www.amiga-hardware.com/showhardware.cgi?HARDID=13).

It's a 2B, which normally has the 2 ports, at least from the pictures I've see in amiga-hardware.com.

Anyway, I still need the f****** connector... or female to male adaptor.

Common.

"Common"

 Great, well at least should be easier getting the cable, I don't want to sell it without it.

That answeres my question hehehehe. Always wondered why the Amiga boards were like that.

The one with teh female connector on the mobo is indeed a little bit rarer (though not much). Instead of a ribbon cable there is a small PCB with the port soldered on and a male connector going there.

@Jose

I think I have one laying around somewhere. I'll send you a PM later today if I find it, and we can work something out.

I had to file and sand down a PC 9 Pin male - 10 Pin header connector in order to make a adaptor for a motherboard such as the one you have just described. I think it was a 9 Pin com port connector that used to connect to a header on the PC motherboard.
Filing and sanding was necessary to reduce the height of the header connector to allow the A1200 shielding to be put back on.
Works fine anyway.

Hodgkinson.

EDIT: Huh? Female connector on the motherboard. Ah. Maybe you could simply use some straight pieces of wire to join the two connectors together? BE CAREFUL though, as sometimes the pin layout is flipped along the axis of the connector - So it would need to be checked first.
Or you could always unsolder the socket from the motherboard and put a standard header there, perhaps (Still necessary to confirm the pinout beforehand...)?

Perhaps Commodore had some plans for another form factor with the same motherboard... or maybe ther was going to be some use for the little door under the diskdrive which needed more space than the longer Motherboard allowed...

Maybe one of the original layout people would be able to answer our question?

Incidentally, we also sell new mouse port cables:

(http://amigakit.leamancomputing.com/catalog/images/9-pin-mouse-pcb-cable.jpg)

We can adapt this cable on request to female for other A1200 revisions.

That's the cable I got but the header on my motherboard is also female...

Don't really feel like soldering it, and while I can use straight pieces of wire it would probable be too loose.
Will try to improvise an adapter or maybe find one on the net, you never know, sometimes after giving up things show up almost by accident :lol:

We have male connectors so could make one up for you very easily.

Wow! The auction Chain pionted to has one:) But I think it's too exprensive for just a connector, I'll try to make my own ripping off some pins on a couple of broken PC motherboards a friend of mine has..

Maybe it looks expensive, but its a original part not a hack, so im pretty sure who need it will buy that even for 5 quids.
ie in infinitiv tower you really need a pcb coz it needs to be holded with screw inside and only connector with flat wire will loose very soon
