More to the point, back in those days motherboards did not exist, everything was valves and hard wired, heck back in the 1970's when I was in the electronics industry, it was still essentially valves, transistors in portable items, and IC's still to come.
My first computer was a atari 400, 16Kb of memory, tape backup, cost me $NZ2200 for the unit with tape deck, 2 joysticks and a couple of games, they were $NZ120 each, games like Space Invaders, Pacman, etc lol on 4 Kb cartridges. That was ah about 8 months pay. Back in 1995 a 486 laptop was retailing here for about $NZ25,000, amazing, looking through some old computer mags from the mid '90 a little while ago.
The first digital watch I saw was a stainless steel case with red LED's that read out hours and minutes, price a steal at $NZ330, at the time about 9 weeks pay for me, and I really thought about buying it, lol. That was about the mid '70's.
So back in 1950, the rapid advances that were to take place just weren't expected, heck they thought that cars of today would still have tail fins and the sky would be full of flying cars and nuclear powered planes hehehe.
