LambdaCore-25Dec1995 works with LambdaMOO 1.8.0p5, with a few fixes here and there. The most important fix is (after loading and connecting to the MOO) to add the support_numeric_verbname_strings property to $server_options and set it to 1. If all you have is 1.8.0, you should get 1.8.0p5 and recompile your server. If you need any more help, please ask me.
