Opening up PSU for Olivetti M24

[Robert Jarratt]

I have just acquired an Olivetti M24. I want to inspect the PSU and I have
removed it from the machine. But I am struggling to remove the only
seemingly removable panel. This is the one with the mains socket and the
on/off switch on it. It looks as if it might be hinged at the bottom, but it
won't pivot out or come away. Does anyone know how to get inside this PSU?

 

Thanks
