I found Jameco has product in stock for $13 at
the data sheet says that each chip has a AABB (year year week week) date of
manufacture string. It appears this is new stock. YMMV

I wrote the firmware for the Paragon II. The firmware resides on the
Microprocessor chip not the RAM/ROM/RTC chip. That chip contains all
the non-volatile memory. The memory persists because of the built in
lithium battery. Buying a new chip presents the problem of how long the
new chip has been sitting on the shelf. The lifespan of the battery is
strictly by time and not by usage. A new chip that was made in 1993 is
just as likely to be bad as the one in the Paragon II.
