I wish 8bitworkshop got more love. It is amazing. From the homepage "Write 8-bit code in your browser. Ever wanted to be an old-school game programmer? Learn how classic game hardware worked. Write code and see it run instantly." It lets you get your feet wet in Verilog without buying the hardware first. This description doesn't do it justice at all so check it out.
