These are shareware versions of the old, classic tank game. 256 color VGA artillery game that allows up to 10 players to blow each other to bits by shooting in the air, around mountains, and in valleys. Tons of configurable options including weapons, defense mechanisms, weather, economics, etc. Can also be played by one person against various computer foes.

Oregon Trail was best on Apple IIe, but I also found someone who made a Windows exe file. The Mac image runs better in emulation if you can get the keypad to work for hunting, otherwise, the Windows exe version works best in a Windows 98 or older computer with real DOS.

Railroad Tycoon is one of MECC's old abandonware programs. I haven't been able to figure out how to exit Railroad Tycoon when it's running, other than to ALT+TAB to a different window and End Task the command prompt window. This really needs a DOS-based computer like Windows 98 or older.

I just came across an old DOS game from MECC when cleaning my office: Super Munchers. Google results seem to categorize it as abandonware, so I'm offering up a copy for download. Key presses don't respond instantly in Windows XP DOS emulation, so if you have a Windows 98 machine sitting around, try it on there.
