||The Model DY-2500 was the first instrument produced by Dynac, which was originally formed as a separate organization from HP.
The Model DY-2500 was the first production instrument made by Dynac,
which was formed as an independent company in 1956 to concentrate
on the increasing demand for special purpose systems composed of
standard "building block" instruments. It was then believed
that these special jobs could better be performed for the time being
by an organization separate from HP. An early "spin-off,"
the company was financed in part by HP and HP employees and in part
by some of Dynac's early employees. HP served as a principal
source of supply for instruments used in the complete systems designed
The name "Dynac" was derived from the Hewlett-Packard
logo in order to associate its products with the quality engineering
and production of HP. The HP
symbol, "hp," was
inverted to create the logo, "dy." Dynac was changed to
Dymec in 1958 to avoid conflict with an existing trademark.
Eventually, the growth in demand for complete electronic systems
and special purpose electronic instruments exceeded expectations
and placed severe strain upon the limited financial resources of
Dymec. Because of the close relations between Dymec and HP and the
complementary nature of their products, Dymec was merged into HP
as the Dymec division in 1959.
