Here is a lot of vintage Texas Instruments TI-99 brochures.
There's a Fall '89 Catalog, in good condition with some page riffling and two quarter-inch tears on the bottom edge. It does not lie completely flat.
There's a pamphlet of TI-99/4A specials from Joy Electronics. It's an old lot of loose papers stapled together, in good shape, with some tanning and one small stain on the back.
The last item is a Quick Steps guide for the TI-99/4A. It is in good condition with some sun fading, a faint stain on the front. It does not lie completely flat.
The photos show condition the best.
