Requires Chrome, Edge, or Brave (WebUSB). Plug the calculator in with a USB cable, click Connect, and pick it from the browser's device list.
Send a batch
Tick the programs you want below (or select a whole category), then send them in one go. The queue sends them one at a time with a progress bar — keep the calculator plugged in and sitting at the home screen (if it is still running a program, press ON first: a busy calculator never acknowledges the transfer, so a send will just sit there). A program with the same name as one already on the calculator is overwritten silently, so sending a batch again is safe.
