Welcome the UO Demo Wiki.
UO Demo or UODemo refers to the Ultima Online Demo released by Origin Systems Inc in 1998 on the UO:Second Age Retail CD. It was as the name hints, an offline playable demo of the Ultima Online game back then. The information in this wiki is derived from reverse engineering the demo consisting of one executable file and one data file.
The name T2A Demo is somewhat of a misnomer, as the server contained within the demo is Pre-T2A. The uodemo.exe file contains both a early UO Client, and a complete production UO server dated to mid 1998. The scripts contained within the demo are nearly complete for the server's timeframe, and even include some preliminary work on T2A era mechanics.
To install the demo you need an Ultima Online:The Second Age retail CD. Good luck has been had finding these on EBay and other auction sites.

UO Demo Files
Files on the UO:The Second Age retail CD
UoDemoInstall.exe is in the root of the CD.
After installing UO Demo you see two files : uodemo.exe and uodemo.dat.
uodemo.exe is the executable, it contains authentic server code and a full client.
uodemo.dat is encrypted using the GOST block cipher [1]. The keys to decrypt the file are inside uodemo.exe. See also .rundir.
Modified UODemo Files
UoDemo+. (UO Demo Plus)
The uodemo+.exe is a modified demo executable to help unleash some of the secrets within.
UoDmClnt. (UO Demo Client)
The UoDmClnt.exe is a modified uodemo.exe to act as a real/pure client without calling the server functions.
