A rough translation of the scroller:
"Hello everyone! Welcome to Seven Sky BBS! You can find antiviruses, crackers, Sierra On-line games, fido software, various utilities, Boris Vallejo painting collection and much more in here!!! +7(343-2)573409, 20:00 - 07:00 (msk)"

For the scroller to be shown correctly a driver with russian font needs to be loaded before the BBstro is executed. The archive comes with such a driver.
