Bill Of Materials (v1.3)

Once you get the KeyBoard PCB, it's time to gather all the necessary components. Make sure you pick up all the component for a particular configuration; some components differs due to the chose options and the desired configuration.

Note

Assume all ICs are in DIP package, resistors are rated 1/4 W and capacitors 10 V or higher, unless noted otherwise.

Class	Type	Qty. (*)	NES*	MD*	Notes
Res. Network	220K - 9 Pin	2	1	2	Only one needed if Using NES controllers.
Res. Network	6K8 - 9 Pin	1	1	1	10K can be used
Diode	1N4148	8	8	8
Button	Push Button 6x6x7mm	40	40	40
MD Socket	Dsub9	2	0	2	Only for MD/atari Controllers
NES Socket	NES Socket	2	2	0	Only for NES Controllers
Socket	IDC-16	2	2	2
Socket	Pin Socket 1x8	2	2	2
Separator	M3x18mm	4	4	4
Integrated circuit	74HC138	1	1	1
Integrated circuit	74HC174	2	2	2
Integrated circuit	74HC245	3	1	3	Only one needed if using NES Controller
Integrated circuit	74HC595	2	2	0	Only for NES Controllers
Integrated circuit	74HC86	1	1	1

Info

The NES or MD columns show the total components needed for this configuration. Check the Board serigraphy for more information.

Warning

Remember to check at the PCB the Components needed for all the configurations check the MD or NES components at the Board.

Note

We recomend that all the IC must be places at DIP IC sockets.

Here you have a Table with the Summary for the DIP Sockets needed.

Class	Type	Qty (*)	NES	MD	Notes
DIP Socket	20 Pin DIP Socket	3	1	3	Check at the PCB the MD or NES sockets needed
DIP Socket	16 Pin DIP Socket	5	4	4	Check at the PCB the MD or NES sockets needed
DIP Socket	14 Pin DIP Socket	1	1	1
