Here’s a visual example of where 8-bit computers came from and where they are now:
On the bottom, a Commodore 64 home computer motherboard circa 1984, running at 1MHz. – original cost about $600.
In the middle, an MIT Handyboard robotics controller circa 1995, running at 2MHz. – original cost about $200.
At the top, an Arduino microcontroller circa 2010, running at 16MHz. – cost… about 30 bucks.
But only one of them can play Tower Toppler.
