This is a little adventure for the VZ-200/300 8-bit computer and the TRS-80 MC-10. It is not hard. It has some random elements that will bring about your demise in arbitrary ways, but if you simply looking for a about 20 minutes of 8-bit two-word parser nostalgia, you could do worse. As with many games of this type, the world can appear much larger than it is, until you get down to the business of real mapping. There are some very subtle clues to help you make guesses about the quirks of the limited vocabulary, which can help get you out of trouble. Or you can simply peek at the listing...

Oh and there's a cute little graphic title page. Nice work unknown author, and the person who revised it for the VZ-200. There are few few errors in the programs handling of the tunnel and the carrying of items, that I fixed in the MC-10 Version, but they won't necessarily stop you from winning. You start each game at a random location. I have added a link to the Virtual MC-10 Emulator (VMC10.exe) on the main page. Enjoy!

In a review I did of the game "The Temple of Apshai." I argued that the early TRS-80 version of this classic RPG should also be considered as a kind of interactive fiction. The reason I argued this was that the TRS-80 version was really so slow and the graphics so spartan, that the main focus of the game really was on engaging with the narrative of the prologue and the detailed room descriptions of the printed manual. The computer program just provided a structure for bringing that narrative experience to a satisfactory conclusion. The Mystery of Silver Mountain is a lot like that. It is a pure text adventure program, but it really cannot be played without the aid of the original book by Osborne Computing in which the source code was published. The reason is that that book contains graphic images (containing visual clues) of the various locations and additional written materials (codes and clues) that are necessary for completing the adventure. The BASIC program does provide a bare bones set of descriptions and it handles and responds to the input (it's a simple 2-word parser). But there would be little point in attempting to solve the mystery using the program alone. So if you want to play this game on one of its various 8-bit platforms (Commmodore, Atari, TRS-80, etc), you should also find a PDF of the original book. Alternatively there are many copies available on the regular used book sites. The puzzles and clues are very challenging, especially due to the added visual nature of some of them. This is not a simple adventure to solve. That being said, it was meant as an introduction to computer adventuring for 8-bit home computers, so it is not diabolical. It was such a popular program in the mid 80's that I would certainly recommend that anyone interested in surveying some of the greats of 8-bit BASIC IF gaming from that period should probably try it.

My only critical comment is that the parsing engine is a little on the slow side. This might just be my TRS-80 version that I played, but I suspect it is due in part to the program being written in as generic a form of BASIC as possible so that it could easily be modified for a bunch of different systems. In other words, it contains many program remarks and no special programming shortcuts (unique to any particular 8-bit computer) to speed up execution. However, the delay is not too bad--I recall some Scott Adam's BASIC IF games being worse!
