Pseudo-random
numbers.
I confess! And corrects his mistake I made in the
description of the random number generator in the ZX-REVIEW
6'95. RND_3 - a pseudo-random bits, and to get
pseudo-word, the procedure should cause 16 times
and this negates the speed of the generator. With a single call
to 15 bits of the old numbers are present in the new number,
adds only one random bits.
The new implementation is devoid of these shortcomings, but
zero is still unattainable. The idea of getting the numbers
practically the same as in my previous generator. Deleted
checking for null value Be careful! The length of the generator
23 bytes are used only registers AF and HL.
1410.

ADD HL, HL

IFC: Sergei have one question: does anyone know which bytes
replace the printer's firmware
CM-6337 to when you turn
immediately established an alternative encoding?
