I’m opening up my PicoCalc way more than I anticipated and the PicoCalc’s keyboard doesn’t like to cooperate with that operation. So for $1 I bought a 5mm sheet of foam from the craft store (in my case Michael’s) and made a small support to keep the keyboard from pushing up on the PCB when the unit is opened. The opening is roughly 90mm x 73mm. I also taped down my screen as others have done. The taped down screen and this foam thing have helped make work inside the PicoCalc much easier.
