The Chicony KB-9820
Guts of the IR receiver and a cut NES front plate. And the hole cut in the front of the NES.
Hole cut in the Black cover. IR receiver purple plastic cut up.
IR plastic in place temp. Looking through the plastic.
Notches cut for the circuit board. Circuit board in place temp.
Front view of sensor placement. Ready for Epoxy.
Epoxied and looking through. LEDs desoldered from circuit board.
LEDs in a 8 pin connector from an old VCR. New leads soldered in.
Close solder points(too close). Rear middle case mount cut off.
Screw mounts Epoxied. Teflon tape added between circuit board and top plate screws.
Circuit board temp install. Circuit board final with lots of hot glue for LEDs.
Hot glue holding wires in place. Another angle.
In the last shot you can see the circuit board connection is quite cramped.
I should have desoldered it, straightened the pins and replaced it upright.
Update: KB/MS external hookup changed.
The PS2 header and RCA/SPDIF jumpers. DPDT switches, 10 pin connector, 2 pin connectors.
Bracket. Bracket in place.
Switches mounted and hole enlarged in case.
Mounted and painted. Wires soldered on.
Wire routing. Hot glued and intake fan.
Rear of case, painted power screws. Front, painted top of dvd drive.
The light paint was a mix of black, white and tan.
The dark stuff was a mix of black and white.
I plan on taking the sticker off a SMB cartridge and try to make the dvd drive look like a cartridge.
The PS2 header diagram in the manual shows the pinout.
The 'External' refers to the PS2 plugs on the rear of the motherboard.
I set up a Double Pole Double Throw switch for each the KB and Mouse.
So that it switches between the internal IR KB/MS data and clk and the PS2 data and clk.
The PS2 already has +5 and ground, so I only needed those to goto the internal IR device.
As for the RCA/SPDIF that also uses a DPDT to isolate the jumpers.
Update: KB/MS Battery power switch added.
This was added to stop the batteries from draining when not in use.
IR KB opened up. Where to cut circuit board and add 2 leads.
Where to clip wire. Switch mounted in case.
Switch mounted again. Wires added to switch.
Prefit. Final, painted screws green(ON) and red(OFF).
