HDD went down and was replaced, later even more parts got replaced over decade, before retiring it totally.
I got those part of bitcoin for free as for registration gift. Maybe, after all, it was related to some website after all like nc50lc said.
Maybe someone remembers who distributed them like that.
I think it could be something like Bitcoin Qt, I mean it had not special name a lot: just maybe few letters.
I believe it was Debian version 7 even older like some pictures given here, and login was not that one to system itself.

But I can not remember much more to answer questions.
I think it is all lost then.
Thanks for all who tried to help.

It was like bitcoin and that is it. Application on Debian Linux to try. Not like website at all. It had login and password much like website. It was like decade ago I am not sure.
It was unimportant at all but now I think reclaiming would give some gains.
I might try to remember better. Already tried to look Debian software lists.

I remember I had bitcoin account with password and some bitcoin in it.
Now that computer is lost long time ago, but I think I still know password and account name.
How can I get my coin back?
Or it is stored on device?
