I have purchased a book entitled "The Explorer's Guide to the ZX-81 and Timex Sinclair 1000". It is written by Mike Lord and published by Reston Publishing Co. a Prentice-Hall Company. The book contains a description of the ROM routines (including the source code for cassette load and dump), a bunch of games, application notes (including the listing of a linear programming program in BASIC), some useful utilities (like RAM and ROM tests), and a few hardware modifications (like RAM expansion cards and an I/O card). All in all I think the book is well worth the $12.95 I paid for it. Sincerly, Jeff Glasson ...!sdcsvax!sdccsu3!ee163fy
