Like the IAS machine, JOHNNIAC used 40-bit words, and included 1024 words of Selectron tube main memory, each holding 256 bits of data.

Two alternatives to the delay line, the Williams tube and Selectron tube, originated in 1946, both using electron beams in glass tubes as means of storage.

For example, an electron is referred to by the letter " e ", and its superpartner the selectron is written " ? ".

The Williams tube would prove more capacious than the Selectron tube ( the Selectron was limited to 256 bits, while the Williams tube could store thousands ) and less expensive.

It remains committed to cell phones, for example, after having sold a cell phone manufacturing plant in the United States to Selectron, from which it now buys cell phone units.

Several types of memory were acquired, including core memory, plasma cell memory, rope memory, selectron tube, magnetic cards, mercury delay line, and fixed-head drum.

In late February, Chackchai led a team of BOI officials that toured seven cities and met with executives of IBM, Intel, Seagate Technology, Hutchinson Technology, Textron and Selectron among others.

The "'Selectron "'was an early form of digital computer memory developed by Jan A . Rajchman and his group at the Radio Corporation of America under the direction of Vladimir Zworykin.

Physicists, with their compulsion for coining funny names, call the so-called superpartners " sparticles " : For the electron, there would be the selectron; for the photon, the photino.
