No, its 42.

Have you considered mercury delay lines?

Does SN7489 contain capacitors?

Everything in electronics has capacitors, inductors & resistors. The
trick is understanding how they work, instead of just trolling with
ignorant questions.

Twin-Transistor RAM does not contain capacitors

http://en.wikipedia.org/wiki/Twin_Transistor_RAM quote:

"TTRAM is similar to conventional one-transistor, one-capacitor DRAM
in concept, but eliminates the capacitor by relying on the floating
body effect inherent in a silicon on insulator (SOI) manufacturing
process."

Another question arises.

Does Twin-Transistor RAM have a longer duration of data remanence --
when power-offed -- than SN7489?
