This is a good PRNG. BTW, a variation of this is used in Jawbreaker
(disassembly coming soon...I hope). From Jawbreaker...

   lda randomSeed
   bcc .skipXOR
   eor #$4D
   sta randomSeed

BTW, Larry Kaplan mentions this was derived from an article in BYTE!
magazine by Don Lancaster. I posted a question about the original article on
[stella] a couple of months back. Just to follow up, I contacted Mr.
Lancaster about the LFSR and he had no idea what I was taking about. He even
said he never heard of a LFSR :confused:

Take care,
