Filed under schematics, this 191 KB PDF refers to the 2SD1223 transistor. In Japanese JIS numbering, the 2SD prefix identifies an NPN bipolar device for low-frequency…

The 2SD1061 is the subject of this 102 KB PDF, placed in the schematic section though it reads as a part datasheet.

Plain 2SC5111 is the whole name of this 245 KB PDF, filed in the schematic section yet most likely the transistor datasheet.

Specification PDF for the 2SC4924 NPN transistor, roughly 79 KB. No manufacturer, package or application appears in the name, only the JIS-style part number.

Covering the 2SA1837, this 173 KB PDF is listed as a schematic but is expected to be a transistor datasheet.

Datasheet-style PDF for the 2N5089, listed in the schematic category at 97.4 KB. The name gives just the JEDEC part number, with no maker or revision stated.

Plain-named 2N3905 document in PDF format, 62.6 KB, catalogued with schematics but most likely a one-part datasheet.

Named 93CXX and sized at 132 KB, this PDF is listed as a schematic but appears to be a generic datasheet for 93C-series Microwire serial EEPROMs.

Catalogued under schematics, this 123 KB PDF is named 80CPT015, a part code in International Rectifier style that most likely refers to a Schottky rectifier datasheet…

A 148 KB PDF named 27lc512, filed under schematics but most likely a datasheet for a low-voltage 27-series EPROM, given how the part number is built.

Schematic in PDF form for a design labelled T76J, 4.23 MB, larger than many in this set and possibly more detailed.

Schematic in PDF format, 847 KB, identified only as M750 with no brand, device or revision stated in the name.

RAR archive of 873 KB carrying code 400-1-4-01-RA, a near duplicate of a similarly named file but slightly larger, so the contents may differ.

PDF schematic named 45IIX, 1.12 MB, with no brand or board revision given. The token may refer to a motherboard or chipset family, but that cannot be confirmed from the…

Schematic archive of about 946 KB labelled J730F, a model code matching the Samsung Galaxy J7 Pro, although the brand is not in the file metadata.

BIOS archive for an X453MA, an ASUS model code, though the brand is not stated; labelled ok new, suggesting a fresh dump confirmed working.

Patched backup of a ThinkPad X240 BIOS, stored as a 5.56 MB RAR archive. The name says the original dump was modified but does not say what was changed, so the patch…

Duplicate firmware dump labelled HP Envy x360, 8.00 MB in raw .bin form, the size of a 64 Mbit SPI chip.

Base file of the G62AMD firmware group, a 2 MB binary with no extension. The label suggests an AMD-platform variant of a G62 model, yet the name gives no brand…

Raw 4.00 MB BIOS dump named G4I, a short code that suggests a G4 variant but gives no manufacturer, board number or revision.

Duplicate (2) of the G4I firmware image, 4.00 MB in plain binary form, with no brand, motherboard number or version given in the name.

BIOS image for an HP Pavilion dv7-600 series laptop, a 2.00 MB raw binary that fits a 16-Mbit SPI flash chip.
