FPGA Macintosh Classic Display

Thanks to Bob for sharing his great project on show and tell! Check out more info on the project here.

I’ve started getting into using FPGAs. They’re really cool because when you use them you’re essentially creating hardware by typing. When you code in a hardware description language like VHDL or Verilog, you’re not writing code that a microcontroller or other processor will execute, you’re actually coding the processor itself, the actual layout of logic gates and connections between them. I had seen an example of driving an VGA monitor with an FPGA to show a pattern on the screen. I decided to see if I could do the same with a Macintosh Classic CRT and maybe push it further.
Here’s the project in action:

  1. Brings back memories of college. My final version was only advanced as your typical screen saver with moving lines around, changing the colors and so forth. Kudos on image porting and printing. I’d like to get back into FPGAs for their advantages, however it would take a while to get the brain gears back into thinking and designing in this medium (FPGA).
