I do remember Nick and John's discussions on who the original chip designer 
was. My point is, since he designed the chip, most likely any inventions that 
would have come about from the design of this chip would more than likely be 
assigned to Tandy/Radio Sh ack and not to the inventor. Only the inventor would 
have his name on any patents as inventor and not the owner of the patent. That is 
the right of the assignee. 

>From the markings on the 1987 date code chips the manufacturer obviously was 
VLSI. They are still in business. I have not searched patents for them yet. 1986 
part appears to be made by VTI. Looks to be a Korean Company that eiher 
packaged it or fabricated the part. Both date codes due have Tandy Copyright 
labeling on the chips. So Tandy would own a copyright of some form of 
information regarding the chip. I am not sure any search will reveal any deep 
intricate details of the chip.But worth a shot.
