The Akai S950 is not too hard to upgrade, and there are not too many options. One upgrade that can be important is to increase the amount of memory that your S950 has, since it can triple your sample time. Before you start though, make sure you don’t forget to unplug the Akai S950 from power. You don’t want to accidentally fry your S950 or yourself.
You can get access to the memory ports to install by taking the bottom off. To make life easier I normally draw a small picture and place the screws onto the picture so that I can put the same screw back into the same spot. This helps so that you don’t accidentally put the wrong screw into the wrong spot and accidentally strip out the metal.
Though as you can see in the picture above, I just place the screws by the holes. This was okay, but if you’re worried about dropping a screw inside the electronics then definitely get yourself some paper and a pen and draw it out.
My S950 didn’t have any memory upgrades, so it was running with the default 750kb of memory. In the picture above you can see that I installed two additional memory boards to get memory up to 2.25mb, allowing for a maximum of 63 seconds sampling time at 7.5khz sample frequency. When installing the boards I made an effort to make sure that I aligned the memory card to the port and pushed with some reasonable force, but I was trying to be careful enough to make sure I didn’t bend any pins.
This upgrade is not too hard, so as long as you are handy with a screw driver, and not too clumsy, I would say this is something an average person should be able to do without too much effort.
