"Nellan is Thirsty" by Dr. Furman H. Smith (1980)

SPOILER ALERT!  The above is a complete walkthrough of the game.

This program is from the July/August 1980 issue of Recreational Computing Magazine.  I have made a port to the TRS-80 MC-10 using Microsoft Color BASIC.  It is a simple text adventure designed to introduce children to text adventure games.  My version of the game can be played online here:

I used Commodore 64 source code.  There doesn't seem to be any easily available original TRS-80 Model I/III code out there.

It is a very gentle and forgiving text adventure.  Hints are provided at the beginning to familiarize players with the basics of two-word parser text adventuring.  However, this does not mean it is without it challenges. There are some subtle puzzles that need to be figured out, which will challenge any neophyte player.

I have made a few edits to the text messages of the game.  Some are just for clarification (perhaps simply my own).  Others are indulgent. I change the name of a university mentioned.  I wonder if Dr. Furman taught at that university?  It's in Texas, but the game otherwise has a distinctly British vibe to it.  Perhaps it is simply its "Alice in Wonderland" style, or it is simply the name "Nellan", which seems so British to me for some reason.

Jason Dyer has a nice write up on the game:

But I can't see much about Smith there. The original article supplies these details:

Furman Smith received a Ph.D. in Probability and Statistics from the Florida State University in 1972, taught three years at the University of Kentucky, and has since been at the University of Houston Victoria Campus. He is currently an Associate Professor of Mathematical Sciences teaching four courses, Chairperson of the UHUC Faculty Council, and a member of numerous committees including an eight faculty member group that is advisory to the President of the University of Houston System. He has a marvelous wife, two marvelous kids, one good home computer, a garden, and backlog of work.

 Nice.  From one academic with a backlog of work to another, thanks for a wonderful game Dr. Smith!
