This is an older book which relates to the Tandy 1000 series of PC-compatible computers.

"Graphics and Sound for the Tandy 1000" was listed in the 1989 and 1990 Radio Shack catalogs for $7.95 as item number 25-1512. It was probably available for purchase in Radio Shack stores.

It also appeared in the 1988 Tandy Computer catalog, which indicated that the book provides BASIC programming commands for sound effects, three-dimensional graphics, and animation.

This book probably applied to the original 1000, A, HX, EX, SX, TX, SL, TL, AX, and RL more closely than the RLX, RSX, or 1000s with EGA, VGA, or Soundblaster add-on cards installed.

Sometimes this item can still be purchased on eBay or one of the web sites that offer used books.
