The other day I was south of Seattle perusing some lesser known thrift stores. Just your typical Saturday morning, when I spy a very cool thing: A TI-99/4A retail box. I inspect the box, and it's full of treasure! A bunch of cartridges, a couple of tapes, the original instruction and basic training manuals, a 1981 issue of computer user magazine, two paddles and an rf adapter. And since it was so close to Thanksgiving/Black Friday, everything was half off. 20$ for a 4A?
