SYNC readers will recognize Dr. Logan as a major ZX80/81 expert whose writings are well worthwhile. Understanding Your ZX81 ROM is no exception. The book is written for a serious beginner who has a fairly good knowledge of Basic and wishes to take advantage of Z80 machine code execution speed. It supplements, but does not replace, the ZX81 manual which must be used as a reference.
