# The Explorer’s Guide to the ZX-81 and Timex Sinclair 1000

About 60 pages of usable insider information (Interrupts, video, block diagram) and 60 more of somewhat undocumented Basic sample programs. The insider stuff does look helpful and a few schematics are provided (16K RAM, PIO, relay driver). This book just might fill in some facts missed elsewhere.
