    A princess walked into Radio Shack holding a frog. And she said to
    the sales person,
    "can you help me with this, my prince got turned into a frog"?

    So the salesperson sold her a TTL 7404.

    With all due respect, that joke goes back to the 70's. :)

    For you young folk, a TTL 7404 is a HEX Inverter.

    I was gonna say,it must be an old joke..RatShak didn't even carry logic
    gates anymore,the last time I was in there,looking for one.
    You'd be lucky to find anything *OTHER* than a crappy cellphone or
    crappy PC in a RS store these days.
     

  6. The real joke is that someone from Radio Shack even KNEW what a 7404
    was.

    I think I read it in a copy of Popular Electronics or maybe Elementary
    Electronics. I can still build logic and solve a Karnaugh map 20 years
    after graduating from college - but heck if I know what goes on in a
    Northbridge.

    You've got questions, they have blank stares (and a cellular to sell you).
     

  10. You've got questions, they have blank stares (and minds).

  11. "You've got questions, they've got pimples".
     
  12. It was different in the TRS-80 era. For a while, you could actually buy all of
    the parts for an 8080-based computer (but not a Z-80, go figure) there,
    and some of their employees were hardware hackers.

    Of course, those were exceptions. I once asked to see the character set
    of one of their oddball printers (the one that had a steel platen drum
    with a star-shaped cross section). It was connected to a running computer,
    so the counterdroid started typing PRINT "ABCD...". I asked him why he
    didn't just use a FOR loop, and got a blank stare.

    That's *so* true. I have three Rat Shack stores nearby, with apparently only
    one competent employee between them. "Hookup wire? You mean speaker wire?"

    They have minds?

  15. Sure, but they come off the same production line as "Dummy
    Components" They look real, and have real leads, but there is nothing
    inside the package..

    There is nothing better than being a hobbyist and seeing them rip out
    25 pair wire.
    I once had 50 feet of that from a place I worked at, and I stripped it
    and cut it up and
    made all my friends in college happy with all this wire they didn't
    have to pay for!
     

  17. 25 feet? you would have freaked out of 16 feet of brand new 200
    pair, or the thousands of feet I've salvaged over the past 40 years. In
    fact, I have salvaged and reused entire 1A2 key phone systems, both five
    and ten line, which used 50 pair.

    Sadly, the metal reclaim depots will not accept insulated wire. The city
    frowns of people burning off the insulation as well.

    Unless you can build a machine that can do the job, it's not economical
    even with the rise in prices.
     

  19. Motor driven metal rollers can crush the isolation, leaving bare
    copper. Some large copiers have nice gear driven roller sets. You only
    need the right speed motor, and a guide plate with holes for different
    wire gauges.

    Does this work only on the individual wires or could a complete CAT5
    cable be run through?

    There was a large copy machine by the building dumpster yesterday
    as luck would have it. I thought of ripping the motor(s) out but didn't get
    around to it.

    When I wired this office I'm sitting in now, I created four five foot high
    piles of CAT5 that were probably 15 feet in diameter, from the removal
    of the old wiring. I'm sure it was good money to someone that could
    strip it.
