Flashing LEDs on and off and reading switches! Understand how everything works off a clk and everything happens at the same time (so to speak?)!
I would suggest getting a Terasic DE-1. There are a lot of LEDs, switches, 7 seg LEDs, etc. that you can play with and at the same time you can bounce back and forth between your experimenting and the CoCo3FPGA project.
I have found that programming the hardware has some similarities to software state machines. It also helps if you've played around with 'real' hardware (like TTL chips and CPUs). But it does take a different mind set than software programming. I've been noodling around with a few FPGA dev boards for almost 2 years now. It's fun but I'm still far from being an expert!
