As seen on the Manufacturer's website - MODEL B is the original Raspberry Pi, MODEL B+ is the higher-spec variant of the Raspberry Pi. It replaced the original Model B in July 2014. Compared to the Model B it has: More GPIO. The GPIO header has grown to 40 pins, while retaining the same pinout for the first 26 pins as the Model B. More USB. We now have 4 USB 2.0 ports, compared to 2 on the Model B, and better hotplug and overcurrent behaviour. Micro SD. The old friction-fit SD card socket has been replaced with a much nicer push-push micro SD version. Lower power consumption. By replacing linear regulators with switching ones we’ve reduced power consumption by between 0.5W and 1W. Better audio. The audio circuit incorporates a dedicated low-noise power supply. Neater form factor. We’ve aligned the USB connectors with the board edge, moved composite video onto the 3.5mm jack, and added four squarely-placed mounting holes.

i bought a "new" one and life continued as normal.
then i remembered i had seen a video on the internet about game emulation of ultra compact computers. i did a quick search and discovered the raspberry pi. it looked like it would do everything i wanted and more.
i tested it out when i got it and found that i can emulate the genesis perfectly, as well as master system and NES. super NES emulation is hit (70-80%) and miss.
i gutted my dead genesis, leaving the small controller board that operates the power/reset buttons and has the controller ports on it. i modified the case to mount the r-pi inside. then i wired the buttons and controller ports to the GPIO pins on the r-pi. i needed to write some custom python scripts to operate the buttons how i wanted, but there are lots of tutorials online.
i now play games with a genuine sega controller. (for SNES games that need more buttons i can plug some wires into the controller end and use my genuine SNES controller, or a usb gamepad.)
after that i started to see what else i could do with this toy computer.
i found software that lets me stream audio and video from my computer and phone to the device.
it works better as a media server than my dedicated WD TV Live Media Player, which cost close to $100.
i even found that i can use my old windows media centre usb infrared receiver and remote.
things for me to still do:
acquire SNES controller ports so that i can wire them permanently into the side of the case.
install a small infrared sensor in the front of the case so that i don't need to use a usb one.
There are tons of great instructions on Pi everywhere, these are great ways to learn Linux/Unix and for around 80 dollars US for one complete card setup, it's fairly cheap as well
There are some horsepower concerns when it comes to actually playing video from the device, as the X GUI doesn't have enough memory (even when jumping the GPU RAM to its max) to load YouTube (just my example, as I had hoped to use this unit to play video from another web-based streaming video service) via Chromium. I haven't tried any sort of command-line playing of video, but I imagine that's a possibility.
All in all, if you have a bit of Linux know-how and an "what if" attitude, you can do a lot of cool thing with this li'l guy.
- Arrived quickly in anti static packaging
- Tiny form factor, can be taken anywhere
- Easy to setup even for beginners, with plenty of online guides
- The two extra USB ports on the B+ are a must
- No good way to shut down the device if it freezes except pulling the power (this is a limitation of all raspberry pies as they do not have a button with a shutdown script).
Great device for beginning projects and I look forward to turning one of these into a custom home security system or anything else I can dream of.
