    The following are images of an electronic devices. I have not been able to identify its origin or purpose and any help or suggestions would be greatly appreciated. The device possibly has an attitude towards telephony or telecommunications. Thanks.

    The large chip (62256) is a 32k x 8 RAM that can be battery backed. Possibly to hold calibration values.

    The 26mHz oscillator tells me it's a cell phone. The TDA1011 audio amplifier cinches it.

    Welcome to ETO, Uladzs!
    Well, since there appear to be connectors that, obviously, must attach to additional devices (Screen?, keyboard, etc.?), and no enclosure(s), quite possibly none of us have ever actually owned or worked on the device to be able to definitively identify it.

    You might try using:
    Search for images with reverse image search - Google Search Help
    https://support.google.com/websearch/answer/1325808?hl=en
    .com to see if google can find more info.
