Because the majority of the modules in the early PDPs *were* commercially
available. DEC's original business was selling logic modules.

I'm certainly willing to concede that some of the modules you cited may well
have been commercially available also; I just was previously unaware of that
fact. But certainly SMS modules were not offered as a product by IBM.

Was CDC selling those modules in 1959, when the PDP-1 was designed?
