Here’s a no-PCB Arduino that doesn’t obscure the DIP ... allowing it to be used in a breadboard or DIP socket. You can see a walk through of the components in the clip after the break.

However, while the Uno is a helpful board for your beginner ... pin headers make it perfect for prototyping with a breadboard. However, Arduino also offers this board without headers pre-soldered.

Compatible with Arduino and Raspberry Pi, it can almost meet all your needs. (Without Microcontroller Board) Breadboard and Power Supply Modules-Include various LEDs, resistors, buttons ...

[Damian Peckett] has implemented an Apple ][, its 6502 processor, and a cassette port, all on an Arduino Uno. If that wasn’t enough, he also uses a PS/2 keyboard for input and outputs analog VGA.
