Catalogued as a schematic, this 75.7 KB PDF is called 2716 and offers no brand or board information in its name.

Short PDF of 54.6 KB labelled 60HQ and indexed as a schematic. Apart from that series-style code, the name carries no device, brand, revision or version information.

Named for the Catalyst Semiconductor 24WC129, this 74.3 KB PDF is catalogued as a schematic but serves as the part datasheet for a 128 Kbit class I2C serial EEPROM.

PDF datasheet for the 24AA014 and 24LC014, compact 1 Kbit serial EEPROMs on the I2C two-wire bus.

Part 3 of a 16M-DRAM PDF series, 348 KB, catalogued under schematics. Apart from the 16-megabit DRAM label and the part number in the sequence, the name says nothing…

RAR archive of 18.3 MB for a Lenovo ThinkPad X1 Nano, with the generation number missing from the name, so the exact model cannot be confirmed.

Schematic marked Sony GD1A in PDF format, 733 KB, with no VAIO model or MBX board number in its name.

R9200 archive with version marker V101, packed as a 347 KB RAR. No brand, board number or document type appears in the name, so open it to find out whether it holds a…
