Full Size Replica not working

[Robert Kent]

I just bought a new full size replica of the kenbak 1 and it barely works. It keeps restarting on its own like every 1 to 5 minutes. I also keeps freezing. Any suggestions on how to fix it?

It's not the usb cable, I've tried various cables.

Its not the power source, I've tried with different phone chargers and even with my laptop usb port.

Its probably not where the cable connects to the kenbak 1, most of the time it restarts when I press the store button.
