I will send to the first person willing to pay the shipping costs from zip 02916 2 hardcover books in very good shape for programming the TI-99/4A. Both books are by Frederick Holtz and include the dust jacket. Both were published in 1983. The first is called TI-99/4A Game Programs. It is the first edition and the first printing. The second is called Using and Programming the TI-99/4A Including Ready-To-Run Programs. It is a first edition and fifth printing. I will ship by whatever usps method you would like as long as you prepay via paypal. Once you say you want the books I will box them and weigh them at the post office to give you an exact cost. Hope somebody can use them.
