Is anyone out there actually tinkering with building a relay
machine? The other day I found SPDT relays for less than a
buck each in a Digi-Key catalog. Seems to me they were $0.81
each in quantities of 100 or more; maybe $1.06 each for 25.
I know NPDT (N>1) is better, but for less than $1 each, this
seems pretty good.
Cheers,
Bill.

I've created a small private mailing list for a few people (including me)
who are (thinking about) building relay machines. You can get relays
pretty cheap at surplus electronic shops, but that doesn't sound like a
bad deal for matching new relays....

Bill,
I've heard that it was tried in the old days but that relays wore out
VERY quickly and they could never get anything larger than a very small
computer to work. In addition, most relays contacts have some chatter and
those caused false signals to be sent.
