"The Endless Tomb" is a "text adventure" and was one of the first computer game I wrote on my TRS-80 microcomputer circa. 1981 (when I was 15).
It was inspired by "Adventure" as well as Scott Adam's text adventures. Both of which I enjoyed.
I remember uploading TOMB.BAS to a local BBS in Houston to be a free download -- a predecessor to "open source". But then I asked the BBS operator to pull it down, because I had submitted it to a magazine for publication.
