Quesion about rerouting calculator


Recommended Posts

hi, i'm working on some project and i need to reroute a calculator (i have casio fx-82ms and a chinese copy of it (which is really different from the inside)) i would like to connect the key's and display to my own micro-controller , the problem is the display , the connection has very small wiring so i can't connect it by hand and i can't develop a board with such small wiring for the screen, the screen size is 64x21 (couldn't find such screens on the net) is there a chance to find same screen but with more simple connection? is there any other way to bypass this problem?

can any one suggest a solution?
