Quoted from Quench:What year did this specific purchase happen?
Are you talking/confusing about when Sam Stern bought 49% of Williams back in 1947, then the rest of Williams in 1959 but then sold it in 1964 to Seeburg?
Is there some other purchase where Sam/Gary Stern obtained access rights to Williams solid state hardware?
I don't know the details, just what Dave recounts in several excellent interviews which are on youtube, he was there at the ground floor of Data East. Stern had rights to the hardware due to the purchase of Williams at one time. How they transferred to Gary Stern I don't have that information. The fact that Williams didn't sue the hell out of Data East for hardware infringement lends some credence to the story. Dave was emphatic that the software had to be developed "clean room" because Williams was so litigious.
For all we know it could be something as innocuous as a "pop bumper" and some court ruled that was "hardware" and thus displays, power boards, mpus qualified but clearly software did not.
I don't know.
