Looks like their website has changed around. They used to have a kit that came with a raspberry pi (that you had to assemble yourself) and their own Linux-based OS that taught you about computers and the command line
It's still there, based on Raspberry Pi 3. The newer models are Intel based w Windows 10s. I'd preorder a Pi 5 and do a project w the kid where you source the pi, case, screen, get an old laptop or two a old router and set up a network lab.
They ripped us off w a Kickstarter, three things first two came the supposed synth that they had Nile Rodgers pitch never shipped and they pivoted to their kid's software basically being a Windows app.
