Step 19Optional Assembly: NeoGeo Converter Option
This step is for the 'NeoGeo Converter Option'. If you are not planning on using the UPCB as a NeoGeo converter (you are going to install the UPCB into an arcade stick), skip this step.
The NeoGeo controllers use a connector that is compatible with the DB-15 standard connectors. We will be taking advantage of that by installing a male DB-15 connector on the right hand side of the board for you to plug your NeoGeo controller into, and installing a female DB-15 connector on the left hand side for you to connect a UPCB console cable to. You will be able to use your NeoGeo controller on any system supported by the UPCB.
Both of these DB-15 connectors will be soldered directly to the UPCB. Pads on both sides have been used to allow this. The thickness of the UPCB should be prefect for a DB-15 connector to snugly fit over, and the pads were desined to line up perfectly on both sides.
One half of each connector has 8 pins, while the other half has 7. Make sure the wider half, the half with 8 pins, is on TOP.
Start with the female connector. Just we are perfectly clear on which is which, check the pictures below. If the connector has a bunch of metal pins in it, it is male. If it has a bunch of holes for those pins to go into, it is female.
Take the female connector and slide the left edge of the pcb between the solder cups. It may fit fine the first time, or you may need to nudge it a little. Either way, you can line up the solder cups over the pads on the PCB perfectly. Check the bottom as well; they should line up perfectly as well. If you see an extra pad on the top, you have the connector upside-down.
Take your soldering iron, and heat up both the solder cup of the top most connector pin, and the UPCB pad we will be connecting it to. We don't care about solder that goes in the cup; it won't do anything. The only thing we care about is the solder connecting the solder cup of the connector to the UPCB pad underneath. Apply solder between the pad and the cup, then remove the iron and let the solder cool.
Check the connect to make sure it is fully against the pcb as far as it will go. If not, melt the solder, adjust the connector, and check again. Once you are certain the connector is properly seated, solder the bottom-most connector the same way. Check your work that it is seated flat against the edge of the UPCB. Once the connector is seated properly with two soldered connections, it won't move. Solder the remaining 13 cups to their respective pads, on both sides.
The male connector is done the same way. Solder the first cup to the pcb, make sure it is seated properly, solder the last cup, check seating again, and if all if good, solder all of the remaining cups to their pads.
The NeoGeo controller can be plugged into the male connector, the UPCB console cable can be plugged into the female connector, and all of a sudden you can use your old style stick to play on the SNES. Congratulations.
There are other options still available to you, although the largest ones (Piggybacking, and the stick/button connections) are not recommended. Putting in an ICSP connector would be a good idea, and LEDs are certainly possible. Please keep reading.
