Existing DNA sequencers, he reasoned, used clunky technology akin to computers based on vacuum tubes.
So why do you have lots of vacuum tubes stuck in lamps throughout your house?
The machine used 18, 000 vacuum tubes to handle the calculations that are now performed by tiny microchips.
DEC's service organisation and its customer relationships, some of which have been cultivated since the days when vacuum tubes were still warm.
His first job was with vacuum tubes, at a company called Centralab.
Terman had promised to find Packard work in some of the local instrument companies, like that of Cy Elwell, who were busily making vacuum tubes.
You mounted the tapes, you flipped the switches on the front panel, you rebooted when things crashed, and possibly even replaced the burned out vacuum tubes.
Lin, Justin, and Marie examined the semi-conductor industry, where the initial reliance on vacuum tubes was replaced by bipolar technology, which in turn was replaced by complementary metal-oxide semiconductors (CMOS).
The lot also includes some handouts that cover Ferractor-based systems, which Univac used in their logic circuits as a magnetic alternative to the vacuum tubes used in earlier computer designs.
FORBES: More Geek Goodies Than You Can Shake a Pneumatic Tube At
However, the jammer currently being used was designed in the era of vacuum tubes, so a competition has been launched to develop a system with more power, precision and versatility.
FORBES: Outcome Of Three Programs Will Drive Defense Sector Consolidation
"Serendipitously, Bubble Wrap and vacuum tubes met, " says Hickey.
Semiconductor transistors were beginning seriously to rival vacuum tubes.
Vacuum tubes have been eclipsed by integrated circuits.
FORBES: In Digital Age, U.S. Military Still Stuck With Vietnam-Era Jammers
My silent digital monologue lead me to wonder what had happened to thermometers filled with shiny but toxic Mercury, watches (with or without hands), cameras with 8mm film, and television sets with vacuum tubes and knobs labeled horizontal hold.
The lessons from disruptive innovation suggest that these technologies may never be as good as the absolute best human tutor (for example, the raw capacity of vacuum tubes still outpaces that of transistors, which disrupted the vacuum tubes in the consumer electronics market), but they will be plenty close.
FORBES: How Machine-Based Tutoring Could Disrupt Human Tutors
The stuff is put through a strainer to remove random debris, then sucked via tubes into a vacuum system that blends it with other polyurethane scraps recovered from car dashboards and shipping materials.
