Scarab of RA

Do any of you know Scarab of RA?

I'm not really into computer games, but this I find fascinating. :) I played it a lot when it first came out. Unfortunately, I think it's only for Mac users.

Here's some info and a link:

Scenario

A freak sandstorm in Egypt has uncovered the top of the Great Pyramid of RA the Sun-God. Already dozens of explorers, singly and in teams, have entered the pyramid through the door at the very top. None have ever returned. You, a lowly undergraduate student in Archaeology, have decided to enter the pyramid on your own and learn its secrets, and (if you can) survive to tell the outside world of its wonders.

In the dark of night, you have crept out of camp and into the Great Pyramid. You have stolen a little food, a lantern, and some oil for it, but that's all the equipment you were able to take on short notice. However, you expect to find abandoned food and equipment left behind in the pyramid by the other, earlier expeditions. (The ones that didn't make it out -- remember?)

You'll find that the pyramid is divided into floors or levels, and each level is a maze whose exit leads to the entrance of the next level down. The exit doors are locked, so before you can leave a level, you must find the key for its exit. You'll also find other things as you explore: the lost and abandoned detritus of earlier explorers, piles of gold left by ancient RA worshipers, dangerous animals, hidden traps. You must use your ingenuity and the tools you find to avoid the worst of the hazards.
