This beast of a TI-99 was picked up at an estate sale. It belonged to a local TI-99 owners club and the old newsletters are all scanned if you google for West Penn 99ers. The Gram Kracker add on card seems like a very sought after peripheral. Buried inside the case is a hard drive and some RS232 add on card. I soldered together a video cable but get no output or signs of life. First I plan to remove the hard drive and do an image if its readable. Then check all the power supply voltages. Some pictures of the beast and crowded interior.
