Component PDF of 133 KB for the 2SA1705, filed as a schematic but named after the part only, with no device or board information.

Small PDF listed as a schematic, though the name 2SA777 with suffix E reads like a discrete semiconductor part number in the Japanese 2SA style rather than a board…

The 1SS398 is the subject of this 78.2 KB PDF, which is catalogued as a schematic but is likely a single-part datasheet.

Only the part number 1SS374 is given in the name of this 68.5 KB PDF, so treat it as a component specification rather than a board schematic.

Labelled 1SS268, this 126 KB PDF appears to be a datasheet for a single component even though the index lists it as a schematic.

Circuit schematic for a model named T42, supplied as a 1.08 MB PDF; the name carries no manufacturer, board number or revision.

Captured status register of a Winbond W25Q64 flash, saved on 3 January 2019 as a two-byte file.

Unlabelled 8 MB flash dump taken from an Eon EN25QH64 SPI chip, with the programmer's timestamp of 10 January 2019 as its name.

Compal LA-6751P documents tied to the G570 and G470 models, compressed as a 971 KB RAR.

BIOS dump for the Samsung NP-R519 notebook, XA01RU Russian configuration, compressed to 952 KB. The name carries no motherboard number or chip type.

Lexicon MX200 documentation in PDF format, about 1.22 MB, indexed as a schematic for this dual reverb and effects processor.

Laptop mainboard schematic for the Quanta Y19C project, revision 2A, in a 3.30 MB PDF. The file name carries no brand, model or chipset details, only the ODM code and…

Schematic for the HP Compaq Presario 2200 series notebook, a 970 KB PDF. No motherboard number, ODM or revision appears in the file name, so check the title block…

TP-Link TD-W8951ND firmware for hardware version 5, dated 160113, which reads as 13 January 2016. The 1.41 MB ZIP should contain the upgrade image.

Tiny RAR named for an HP charging-port check, only 132 bytes. An archive this small cannot hold a schematic or firmware; it probably contains just a short note, a link…

1.03 MB RAR archive for the Samsung NP-R60 laptop. The name does not say what is inside or give a board code or revision, so extract it and check whether it holds…

Schematic for the HP HDX9000 series notebook, built by Inventec under the project name Orion.

ASUS X553MA laptop schematic, a PDF of around 1.17 MB; the RG suffix in the name is not explained and may mark a board revision or variant.

PDF schematic labelled UL20A, a 1.32 MB circuit diagram for the notebook mainboard carrying that model designation; the name gives no board number, revision or brand.

Motherboard schematic for the K42JV notebook, revision 2.0 as stated in the file name, supplied as a 2.44 MB PDF.

Datasheet in PDF format for the 2SC4161, 130 KB in size. The 2SC prefix in Japanese JIS numbering identifies an NPN bipolar transistor, and the sheet should give voltage…

Stored under a lowercase name, this 52.3 KB PDF covers the 2sd2318 transistor. In the Japanese JIS scheme the 2SD series contains NPN devices for low-frequency duty, so…

PDF reference of 221 KB for the 2SK2909, catalogued as a schematic. Only the part number is present in the name, with no maker or revision indicated.

Component sheet for the 2SK2886 transistor, delivered as a 424 KB PDF and filed in the schematic category. The name carries only the part number.

PDF document for the 2SK2775, filed under schematics although the part number points to a component datasheet rather than a board drawing.

Component document for the 2SK2611, a part number in the Japanese JIS scheme where the 2SK prefix marks an N-channel field-effect transistor.

Compact 33.0 KB PDF on the 2SK1834 transistor. The 2SK prefix belongs to the Japanese JIS designation system and means an N-channel field-effect device, so the content…

Datasheet-style PDF for the 2SK1412LS, a Japanese 2SK-series N-channel field-effect transistor, filed in the index under schematics.

At just 31.4 KB, the PDF named 2SJ499 is probably a short datasheet or summary sheet, even though it is filed as a schematic.

Catalogued as a schematic, this 93.1 KB PDF is named only after the part number 2SJ281, which follows the Japanese JIS scheme where the 2SJ prefix denotes a P-channel…

At 294 KB, this PDF is larger than its neighbours but still identified only by 2SJ167, a Japanese JIS number for a P-channel field-effect transistor.

PDF document of 41.7 KB for the 2SC4737, filed in the schematic category but named after a part rather than a board.

Filed under schematics, this 98 KB PDF is named after the part number 2SC4671, which follows the Japanese JIS designation for an NPN bipolar transistor.
