Quoted from zacaj:
70s ems were about $800 from distributors. Later 90s games 2-3k
The Williams and Bally games produced by Williams in the mid to late 90's had a BOM cost of about $2000 +/- $100, and if I remember right, the labor was about $250. I believe we sold to distributors for around $3000, which left gross profit of about $750. The year we produced 70K games, that was an annual GM of about $52 Million. Of course, there were mouths to feed.
