This
rare treasure is a Core Magnetic Memory Card from Litton and used
by space programs of the 1960s and 1970s for their inertial navigation
systems and called LTN-51. Inside are six, 6, layers
of core in two,
2, sections each. On opposite side are supporting
electronics and
sides having the old PNP transistors. This was made
in a special
manufacturing process for the space programs so the core memory would
not be affected by orbital radiation. Inside core
memory is surrounded
by .25” steel plates and visible supporting electronics have a Lucite
substance to protect from any moisture or other
hazard. Note the old
PNP transistors on each side and wire wraps at
bottom. It is stamped
“ASSY 2-00059-301-001, IGC SER 0307”. Size is 7.5 x
4.5 x 1.25 inches
and weighs 3 lbs. These are very nice to display as
they are part of
our space and computer history. See
http://www.ed-thelen.org/.... This
will highlight any collection of antique computer memorabilia.
