I am looking for an expansion box for a TI-PRO that I have loaded and need to address more boards. Such a box was sold in the mid 80's by ARK Technology of Cleveland, OH. They went out of business in 1986. Does anyone know how to get in touch with the Principals? Perhaps they have some inventory, and I could buy one. They had a representative in Mountain View, CA called Master Reps. They too don't exist. Anyone know how I could track someone down from Master Reps. Alternatively, does anyone have such an expansion box they might want to sell? Or another alternative, what action might be needed to make an XT expansion box work? I have such a box. If the transimitter board is put in the PRO, the machine will not boot. If the receiver board is put in the PRO, the machine will boot but will not recognize boards in the other box. There is a -5V pin on the receiver board that is dead in the PRO. I guess no -5V distribution. Could I safely use a voltage divider from the -12V bus? EMAIL to Frank_E_Emery@cup.portal.com Thanks in advance.
