Pseudorandom number generator for Z80

This code implements the same pseudorandom number generator formula used in the Sinclair ZX81 and ZX Spectrum computers, but it's faster because it doesn't use the calculator routines. The quality is fairly good, but the speed is not so good.

The comments tell the rest of the story; see prng.asm.
