I think he is talking about something different. The difference is like this: A 5 dollar plastic keyboard vs. a handmade $1000+ keyboard with mechanical switches. The very first Lisp Machines were handmade $100000 pieces of hardware. With wire-wrapped boards made of zillions of low-integrated chips and various other components. Huge power supplies for several KW worth of electricity. Really everything was specially made, like 25m long console cables with signals for monitor, mouse, sound and keyboard.
