A small Lisp-Machine in an FPGA (aviduratas.de)

Bonus points for "Wahrscheinlich guckt wieder kein Schwein" - that triggered some fond childhood memories. ;-)

The verilog code had been poorly written. For example, it's not common for a combinational circuit to have an input reset. Latches are inferred in some places that can cause unexpected behavior. That's just my observation though. It's cool to see projects like this. Sadly, it appears to be inactive after seeing the project log.
