ZMUD
Zugg's MUD Client is a MUD client developed by Mike Potter. Version 1.0 was released in December 1995 as a Windows port of the TinTin++ Unix MUD client. zMUD was initially licensed as freeware, but Mike Potter realized that he could make a living from sales of the client and started selling zMUD 4.0 as shareware in September 1996.
zMUD supports Telnet and several enhancements to the Telnet standard such as MXP, MCCP, and MSP. zMUD is particularly noted for its botting and mapping capabilities.
A new client named CMUD was released by Mike Potter in June 2006.
