ATARI Asteriods ROM Chipset (version 2). got one of the old time games?? How reliable do you think your ROM set is? ROM chips are
       only guaranteed to retain their memory for 12 years..ARE YOU ON BORROWED TIME? 2000-1979 = 21 years. The answer is obvious.
       Pick this up, hide it away and then when you need them... there they are ready to give you another guaranteed 12 years worth of service.
       This is a small price to pay for gaming insurance. I charge 75/hr to repair video games + parts. A detailed set of installation instructions will
       be included with your set. Winning bidder to add $5 for shipping & packing. GOOD LUCK...I may not run this offer frequently due to time
       constraints.

hint: what happens if you leave these in a drawer unused for 12 years :-)
