Hi Dave,
Thank you for the small tutorial. I had a few problems getting it going, being that I have learned to run before I can walk, but persistence paid off, and I was able to generate the qwork directory. I loaded the de1.sof file, and had a look through the de1.vhd file. I don't know if I missed a small step, but I am unable to see a top level design. I am using Quartus II 64-bit, windows 7, version 13.0.1 Web Edition.
Other than that, I was able to see the green LEDs count up in binary ( Very cool!!! Makes me miss the 8-bit days =] ) and also the switches could cycle the red LEDs. I also observed the hexadecimal display counting as well. How do I view / generate a top level design? I did compile the design, but ended up with a few error messages:

On a good note, I seem to have gotten a step closer to porting Grant Searle's Multicomp to the DE-1, and get it to boot to a blink cursor with a blinking "d". That tells me video ROM isn't set up properly. I was able to assign pins to the SRAM, but have not figured out how to "route" the video the SDRAM, and have not figured out how to port the ROM "outside" of the FPGA and onto the FLASH. I "think" I can simply copy the BASIC.HEX into the flash, but I don't know how to "connect" the flash to the FPGA in the "program" ( Sorry if I use the wrong terms here... still learning quite a bit... =] ).
Thanks again for everyone's help!!! I truly appreciate it!!! =]
