23 May 80 is the date of final test.
62, 75, and 73 are the hexadecimal addresses of defective minor loops.

Yep, they are. Just last weekend I picked up a TI publication regarding
the TIB0203. I transcribed some of it to
www.decodesystems.com/tib0203.html

 From that same manual: "The TIB0203 is mounted on a 14-pin dual-in-line
lead frame and encapsulated in an electrically nonconductive plastic compound.
Included in the package are the two coils that provide the rotating magnetic
field and a permanent magnet. The package is surrounded by a magnet shield
to protect it from external magnetic fields. The package is intended for
insertion
in mounting hole rows on 1.200-inch (30.48-mm) centers. Tin-plated leads
require no additional cleaning or processing when used in soldered assembly.
The package weighs approximately 25 grams."


Cheers,

Dan
