I got this calculator as part of an X68030 system set. At first I didn't think too much of it, I've seen these calculators semi-frequently, but I went to do a Google search for it because I wanted to know how people refer to these devices. So I searched for "X68030 電卓" and when I wasn't making any headway with that, I tried "X68030 calculator", but this too returned surprisingly little in terms of reference.

I thought something was off and then I noticed that most of them said X68000, not X68030. Searching for "X68000 電卓" provided me with a lot more data, but indeed there was almost nothing for the X68030 version. So maybe it's on the rare side.

But that doesn't necessarily make it *interesting*! The front cover changed (the X68030 replaced the X68030 lettering and the overall design became simpler, but the functions appear to be identical. A curiosity, anyway!
