[cctalk] Re: Relay computers

[dwight via cctalk]

Bob Rosenbloom started to make a relay computer, using pc boards, but found 
that typical dip relays talk to each other ( leaky magnetic fields ) .
Konrad Zuse made several attempts but making useful electromechanical memory 
was his down fall.
As a kid, I used a handful of radioshack relays to make a sequenced electrical 
lock. One had to enter four each four bit numbers to turn on the lock. Any 
wrong number and you had to start over. I think that was first the first time I 
did a logical design. You'd set the 4 toggle switches for the next number in 
sequence and then enter it.
Not a computer but then, I was just a kid.
