Snowplow

According to Leonard Herman, this game was shown at the January 1984 CES.

Description: You operate a snowplow which must clear the eight horizontal rows of snow. Snow is cleared by merely moving your plow through it. Somewhere in each row you'll uncover a car which will then move across the row that it is in and must be avoided at the risk of losing a turn. When all the snow has been cleared, one of the six cars will flash on and off and you must get to it before time runs out while still avoiding the other cars. When the car has been reached, another car will begin to flash. After all six cars have been retrieved, you'll move on to a harder screen where you must again clear the snow.

After Sunrise Software folded, the rights to their VCS catalog were apparently acquired by Telegames, who eventually released Glacier Patrol and reissued Quest for Quintana Roo in 1989. Yet, for some reason, Snowplow was never released. What happened to the prototype that was shown at CES is not known, and thus far the game has never turned up in any form.
