Well, my dad collects old hardware in his retirement leisure activities. He actually has several 12 and 16 inch modules of ferromagnetic memory cards, with 144 and 576 bit memory capacity respectively. That has been a lot back then in the era of the 50ies mainframe machines... 2nd generation computing (using the first transistors instead of vacuum tubes) is a very interesting topic for the hardcore nerd and something to turn off any conversation for nearly the rest of mankind ^^. Man, I miss the ddo servers open already .
