Quoted from tcore:I was thinking about how expensive the new machines are now, but $2800 for Black Hole would have been a lot of money back in 1981.
Just for fun I ran those prices through an inflation calculator website. I don't know how accurate it is, but I'm guessing it's somewhere in the ballpark.
Black Hole at $2800 in 1981 would be equivalent to $7068 in 2013
Theatre of Magic at $3400 in 1995 would be equivalent to $5135 in 2013
Medieval Madness at $3600 in 1997 would be equivalent to $5191 in 2013
