It did not help at all. I found stuff out though:

I did now notice that if I cannot switch it back on, I can reset it with the magic reset D+ON, which I found in a paper for synthetic programming on the hp 15c (on which the combo is y^x + ON which are the same keys).

even more interesting, the calculator then returns and works fine, it even changed the wordsize correctly. So to change the wordsize I have to type 8 WSIZE (calculator switches off) D+ON (calculator switches back on) CLX (because there are weird values in x, see above link).

So, the device obviously is broken, but kind of usable. Does anyone have source for another broken device or the ICs?

edit: i have here the combination of 1LE2-0322 and 1LF5-0301.
