http://whats.all.this.brouhaha.com/category/computing/retrocomputing/retrochallenge/

On the XC7A100T-1FGG484, which is the slowest speed grade, it meets timing
at 62.5 MHz.  Since my 1802 core only needs one clock per machine cycle,
versus 8 for the original CDP1802, it runs at the equivalent of a 500 MHz
CDP1802.
