This is a Texas Instruments TI-99/4A computer that comes with the manuals, AC adapter, and "The Attack" game cartridge in its original box!The computer looks very nice, however we haven't tested it, so we don't know for certain whether it works or not. We're offering it for sale as-is, and won't be accepting returns. Please see our photos for more details, and feel free to ask any questions you may have before making your purchase.
