Hello everyone
in this video we will be looking at not one..
but two Super Nintendo Entertainment Systems
both these consoles are AU version
and we will start with this one
but before we take it apart let's take a quick look at the console itself
this is the label here
it shows that this is the Australian PAL system
here we have the power input and the signal output
which is the same thing with the other console
on the front we have two joystick ports
this is here is the cartridge slot
and the eject button
if we switch the console on it will lock the cartridge in its place
it's a very nice touch
this is the expansion port hidden here
now, let's take it apart
it uses security screws, or as they're called Gamebit screws
done with that, now let's have a peek inside
that's how the cartridge get locked in place when you switch it on
let me clean it a little bit
then we will have a closer look
this is the eject mechanism
see how it works, very simple
this is the power switch
and here we have a big heat sink to dissipate all the heat from the power regulation
let's keep digging shall we
OK
now we can see the beauty
we have more screws to go
alright, this is the motherboard
we will take a closer look at these chips in few minutes
but first let's clean the plastic
OK, now let's have a closer look at the board and compare it with this one
which I already removed all its screws
here are the two boards
Now let's take the heat sinks off
to reveal what's underneath
no thermal paste here
OK, let's see what we have here
they are identical,
almost
these RAM chips are made by HITACHI
while here they are made by MOTOROLA
this metal box is the RF module which is shielded
this is the Audio section
we have two processors and two RAM chips
and on the other side we have the picture processing units
the two RAM chips here are branded Panasonic
while on the other console they are made by NEC
Here we have a Work RAM and another CPU
same goes with the other console of course
these are the two audio RAM chips again and the two audio processors
and on the other console
OK, let's wrap it up
Here we have two RAM chips
and these two are the Picture Processing Units
the PPU
this is another RAM chip
which is 128K
and here we have another processor
on the other side we have two sound processors
The S-SMP
and the S-DSP
and also here two RAM chips for the audio
and there are 5 more smaller chips
see this bar here which holds the eject mechanism
in this console it looks like this
while on the other one it looks like an (L) shape
this is the only major difference
all the other differences are minor
like the different components that are used, and the prints on the PCB
also these plastic levers for ejecting the cartridge
one of them has smooth surface and the other has texture
and finally
we have silver screws on one console and the other one has golden screws
this is the end of the video
