Machine Language Teaches the ZX80 to READ

In Part 1 (SYNC 1:5) we saw what a READ statement is, how it functions, how to run a machine language subprogram with the USR function, and how to get your machine code into memory with Basic loader program. In this part I will give you the machine language READ subroutine, present a few tips on how to get it running, and describe a couple of the features of the Sinclair system that I made use of when I wrote it.
