Does anyone here have this strange device? It's clearly an ES series calculator, but it's a financial calculator, not a purely scientific one. Does it have known bugs and/or exploits? Classic ES series exploits don't work here at all due to a very different menu system, e. g. the AC key is never active in menus and the ON key throws directly into COMP mode.
