Steve B wrote:The problem with the Tasc co. were regarding their Smart Boards
it turned out they did not have the legal right to copy the piece recognition scheme and were forced legally to stop making the boards for use with their R30 units
soon after this they went out of business
Steve S posted alot about this issue when these boards were first created in 1997-1998

Which did they use, Magnetic Fields or Radio Frequency?
I think it's a lot of B.S. actually. DGT uses RF and gets their arrays from Texas Instruments.

Yes, but it's electromagnetic, not electrostatic, or is it? Hmmm...maybe? Still a very old technology.
Now I want to know which it is
Curious Regards,

actually i dont know the details of Tasc's infringement on the pieces recognition scheme used
but i do know they eventually agreed to stop using it
if you look up the posts on the old CCC i think you will see alot of discussion about this between Steve S and even De Koinig who used to post here in those days
