There is a calculator up for auction that i don't think anyone here would be interested in buying but it sure looks to have been influenced by the Voyager series in looks and the 41 series in capability. The introduction date of '83 is about right for those too.
It's here.
I never saw one before but i bet the keys don't click and the batteries don't last 20 years. I'm practically sure there's no flying goose when it's running a program. There's no enter key either. Still; "imitation is the sincerest form of flattery".
