Long Lost

A number of programs I've written are now unfortunately long-lost.  The majority of these were written using Turbo Pascal.  I'm listing them here for memory's sake:

• Dissimiliation: The beginnings of a BBS door game.
• An unnamed, scriptable BBS door adventure game.
• An unnamed LOGO interpreter.
• Tradewars Mall: A "mall" add-on to the BBS door game Tradewars 2002 (?).  Was a clone of another mall.
• Shell-ter: A DOS file-manipulation shell (written in QuickBASIC).
• A number of BASIC games for the Wang Personal Computer, including a star-wars style text game adapted from an issue of Family Computing magazine and a truck-jumping-over-filled-circles-and-falling-down-holes game.
• Numerous Coleco Adam programs written in SmartLOGO and SmartBASIC.

Let this be a lesson: always save every program you write, no matter how unfinished or unpolished it might be.  :)

Update: I think I managed to pull my LOGO interpreter from an old backup CD.  Might be one less long-lost item.
