Wow that's really quite beautiful.

Piano wire for memory??? Wow the things we take for granted these days.

For interest's sake, the EDSAC reconstruction[1] will be using taut-wire delay lines in a similar way as a replacement for the original mercury-filled tubes. We very nearly revisited the delay line "juggling" memory a while back when it seemed that magnetic bubble memory might be the solution to all of our woes. (Then flash happened.)

Very nice. I got see two of these machines as well recently. The memory is indeed quite fascinating. And I totally understand and share that guy's fascination with bringing back things from the past.

Man, I love personalities like Cliff Stoll's!

I mean, if a person can make reverse polish notation sounds like the most interesting thing you have ever learned, they are worth listening to!

Fascinating read:

I hate to admit that I used one of those things in college.

It's a stack machine, like HP calculators.
