A picture says more then words but having something on your hands is even better. I found lately that an German company is manufacturing small FPGA and PLD boards with an DIP24 (GAL like) socket header. They looked nice but when actually having them in my hands, well I instantly wanted to check something out. And I did, and I liked the easyness and fun I had, here is the story
full project (from schematic design to working proto!) was done within 6 hours.
those tiny modules are made by OHO
Ohooo!
