In mid-1980s, a small company called Mark Data Products released 6 parser-based graphic adventure games similar to early Polarware and Scott Adams titles. While the games are reasonably successful on Tandy's CoCo computer, the IBM PC versions did not achieve the same level of success.
While the graphics are quite good at the time, the parser is quite primitive - only simple verb+noun constructs such as GET HAT are understood, and some verbs that are common in IF games such as SEARCH are not always recognized. Fortunately, the games make up for primitive parser with well-written plot, fun characters, and some clever puzzles.
The plot of Trekboer: "This exciting adventure begins abord the starship TREKBOER in the 21st century. Life on Earth is threatened by a deadly virus and your mission is to search the frontiers of space for the cure that will save mankind from disaster. But how? Where? The name of your starship provides the first clue."
Thanks to the generosity of Bob Withers, co-creator of these underdogs who put both the games and their source codes up on his website for free download, you can now experience a forgotten past of the early days of adventure gaming. All are recommended, but if you want the best of the bunch, I highly recommend my personal favorites: Trekboer and Calixto Island.

Comments and reviews
'Trekboer' is not related to Star Trek. From Wikipedia:
"In the history of Southern Africa, the Trekboere (now referred to as "Trekboer" in English; pronounced: /ˈtrɛkbuːr/) were nomadic pastoralists descended from European settlers on the frontiers of the Dutch Cape Colony."
Quite how that fits in with the game I don't know, but Trekboer is the name of your spaceship. Perhaps there's a possible destination planet in the game with a name related to Trekboer history. Sounds intriguing enough to download and play, though.
Very unusual name to use for a science fiction game. I'm certain that the presence of Trek in the name was to be the clue that this was that type of game but a "Trekboer" is an actual thing, a person to be exact. Now as to the "boer" part? Although in 1984, or whenever in the early 80s this game was made, I don't suppose that too many North American game players would have blinked at the name or bothered to look it up.
No comment nor review for this game at the moment.
