The FPGA Development Board

In August 2007 I finally decided to purchase an FPGA development board. I chose the Digilent Spartan 3E Started Board, which is actually still available for the same price I paid 3 years ago… I’m not sure if that is a good thing or a bad thing? Anway, I made my choice based on a […]

The code assumes VDP graphics mode I (the default) and includes the VDP routines I wrote as replacements to the ones […]

I have a good friend, Mitch who lives in Kentucky, and recently married. He was up visiting for […]

I live in a small technology-proof town somewhere in Michigan, I’m somewhere between 30 and 40 […]
