I want to use the LCD display from a Casio fx-85GT X classwiz calculator as I think it will be a fun and challenging project to figure out the display protocol and connect the display to a much more capable processor on a custom PCB; then I could program a calculator with more interesting functions and have control over the firmware.
I need a way to connect the 0.6 mm pitch roughly 35 pin surface mount pads (shown in the attached photo) to some pin headers so I can control the display with my arduino or teensy 4.0 through a voltage divider.
So far I have tried using an old elastomeric connector I scavenged out of an energy monitor to connect it to pads on a breakout PCB with the same pitch, but the connection has a very high resistance when there is continuity at all.
What other options are there that I could use aside trying to find and buy a COG LCD with the same dimensions instead?
Thank you in advance for your ideas and suggestions.
