At Goodwill I got a book titled BIT BY BIT An Illustrated History of Computers by Stan Augarten for 25 cents and it has lots of great pictures and stories in it. At another thrift I got a TI-99/4 with power supply and nothing else ( It's the 99/4 not the later 99/4A). It's in pretty good shape with a few dents. Looked for the Doc's for it but only found TI-99/4A books.
