Here's a brief overview of what's new
•Dual step-down (buck) power supply for 3.3V and 1.8V
•5V supply has polarity protection, 2A fuse and hot-swap protection (so you can plug/unplug USB without resetting the board)
•New USB/Ethernet controller chip
•4 USB ports instead of 2 ports
•40 GPIO pins instead of 26. The top/first 26 pins match the original layout, 9 additional GPIO and 2 EEPROM Plate identification pins
•Composite (NTSC/PAL) video now integrated into 4-pole 3.5mm 'headphone' jack
•MicroSD card socket instead of full size SD
•Four mounting holes in rectangular layout
•Many connectors moved around
There is TinyBasic for the Rasberry Pi and I was also thinking that for $40, I think it is possible to add a system to the 6502 family of chips if you want something cheap to control because there are now 40 GPIO pins.
