I see that your site does not have the complete Abermud code from 1989 (only 4 files). I do have the complete original zipped and I would be happy to make it available to you. Contact me if you're interested. It's a complete C source code (converted from B so there are lots of wonderful typecasts).
For those of you who are interested in developing a MUD from scratch, check out www.matrix-mud.com -- it's my site that treats every aspect of MUD development without snooping around from other MUDs.
