PDF of 541 KB named only with the number 75006379, with nothing in the name identifying the device, maker or part it describes.

Numerically named PDF, 75003177, of 289 KB, catalogued as a schematic but with no indication in the name of what part or device it covers.

Indexed as a schematic, this 118 KB PDF carries only the number 271024, which most often points to a 27C1024-class 1 Mbit parallel EPROM datasheet, though the name alone…

Only the number 271001 appears in this 134 KB PDF name, and it is listed as a schematic, though the pattern suggests a 27C1001-style 1 Mbit EPROM datasheet rather than a…

Listed under schematics, this 92.0 KB PDF has a purely numeric name, 27256, with no manufacturer or revision attached.

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

Catalogued among schematics, this 115 KB PDF is named simply 403DMQ, with no suffix indicating a voltage variant and no device details.

PDF document of 112 KB, indexed as a schematic under the name 70u-d. The name gives no device, manufacturer or board number, and the suffix after the dash is not…

Catalogued as a schematic, this 130 KB PDF is named 64LCXX, where the XX looks like a placeholder covering several capacity or variant codes of one series.

Filed as a schematic, the 103 KB PDF 63ctq100 gives no device model, brand or board revision in its name.

PDF catalogued as a schematic, though the name 27lc4096 reads like a component part number in the 27-series EPROM family, with LC usually marking a low-voltage CMOS…

Labelled 30epf02, this 160 KB PDF is listed as a schematic but the name reads as a part number for a discrete power diode or rectifier.

PDF of only 14.4 KB with the name 25C010, kept in the schematics section. By common naming, 25C010 refers to a 1 Kbit SPI serial EEPROM, though the file states no…

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.

Catalyst 24WC128 serial EEPROM documentation in a 55.9 KB PDF, indexed as a schematic though functionally a datasheet for a 128 Kbit two-wire memory.

Short PDF of 76.2 KB covering the 24C16, a 16 Kbit (2 KB) serial EEPROM accessed over the two-wire I2C bus.

A 220 KB PDF named after the 24C02C, with a -1 suffix that likely marks a duplicate or alternate copy.

Datasheet in PDF covering the 24AA512, 24LC512 and 24FC512 serial EEPROM family, filed here under schematics.

Component documentation in PDF, 122 KB, for a device numbered 23c128. By common convention a 23C part is a mask ROM, here with the number suggesting 128 Kbit, but the…

A 176 KB PDF listed as a schematic and named 20ETS08S, with no device, board number or revision given.

The 208 KB PDF named 20CTQ150 is listed as a schematic, yet the name reads like a discrete component part number, not a motherboard identifier.

Small PDF of about 74 KB named 8EQ045, filed under schematics. The name looks like a power diode part number, likely a Schottky-type rectifier in International Rectifier…

Lenovo schematic in PDF form, 1.16 MB, named only with the code 80A. That token gives no clear model, board number or revision, so open the document and read its title…

Circuit schematic for the Lenovo IdeaPad Y470, a PDF of about 1.13 MB. Only the model is stated, so the ODM board code and revision must be read inside and checked…
