Does anyone out there have two of these Sphericular displays that they may be willing to part with? I have four of the Burroughs ones and would like to add two more to complete a clock design. I have the electronics ready and the software is nearly there, I have replaced the incandescent bulbs with leds which I appreciate may detract from the authenticity of the devices, it does remove all issues associated with turning bulbs on and off repeatedly. - Richard
