Don't forget that data saved in FAMOS (Floating Avalanche Metal Oxide Semi)
memories like 2732, 2764, etc is only guaranteed for a mean of 100 years!

I guess I'm thinking of early-sales versions of computer-controlled gear
that were shipped with EPROM instead of real ROM.  For example, the first
person in our group who got an H19 got two 2716s, the next got two 2316s
(same pinout hard ROM), the next got one 2732, the next got one 2332 etc.
