Does the HP Prime have HWRNG?

No, a hardware random number generator (Or TRNG) does not need a seed. On the TI cc1310 it uses: "The TRNG is built on 24 ring oscillators that create unpredictable output to feed a complex nonlinear combinatorial circuit.That post-processing of the output data is required to obtain cryptographically secure random data."
