Hmm I’m assuming you’re using the Raspberry Pi Pico that shipped with the PicoCalc? I recommend using a Pico2w (that’s what I tested the above script on)

In a future release, I could look into moving some of the MMBasic buffers into PSRAM (we have about 7mb free). I did plan on moving the audio buffers into PSRAM too (which would free 32kb)
