With all the talk about WWV/H/B going QRT I am taking a stab at building the GPS controlled clock in this PDF: http://w8bh.net/avr/clock.pdf W8BH used LED displays, which are power hungry, so I decided to swap them for LCD displays from old radio controlled clocks. So when an old SkyScan clock popped up at a thrift store for $3, I grabbed it. After I dismantled it I noted that there only seems to be a single black wire leading from the motherboard to the display, and this wire is labeled GND on the motherboard, strangely enough. There is a 4 wire ribbon leading from what apparently is the radio receiver daughterboard to the motherboard, right next to the black wire. On the motherboard the LCD is labeled "IS15030". Google turns up nothing, and there is no documentation, such as schematics, for this clock. The clock is pretty old-the boards are copyright dated 1999 and 2000. Does anybody have any ideas? Should I just bite the bullet and try to find a NOS display somewhere?
