@TechConnectify I think there was no reason for RCA to put more effort into making those.
They already knew there were multiple better technologies that would become viable in a few years, so they just quickly came up with a cheap stopgap solution.
Also, regarding those silly "selling points" in the datasheet - what if they were trolling?
What if the entire product line was a joke to see if the management will let them ship something stupid?
