BIOS archive whose name only reads 1020 G1, a 6.35 MB RAR with no brand listed, though the model code matches HP's EliteBook Folio 1020 G1 naming.

RAR archive with a BIOS for the Quanta-built board DAH98MB38B0, revision B, reported 100% working.

BIOS archive for the Quanta motherboard DA0Y0PMBAE0, with no revision, chip size or tested status stated in the name.

Datasheet in PDF form for the HEF4093B, a CMOS logic part from the HEF4000 family, best known as a quad two-input NAND gate with Schmitt-trigger inputs.

Datasheet in PDF form, 74.1 KB, for the 2SD1853 transistor from the Japanese 2SD family of NPN bipolar parts, filed here as a schematic.

Short 34.2 KB PDF for the 2SD2261, an NPN bipolar transistor from the 2SD family, catalogued as a schematic though the content should be a brief datasheet.

A small 33.3 KB PDF covering the 2SD330 transistor, listed as a schematic though it documents a single discrete part. The name carries no other details.

Datasheet for the 5LN01SP in PDF format, roughly 28.0 KB, indexed as a schematic. Only the part number is stated; LN in this series appears to denote an N-channel…

A 40.6 KB PDF for the component 5HN02C. Although classed as a schematic, the file name contains just a part code, with C probably denoting the package, and states no…

PDF specification of about 78 KB for the 2SD1799 NPN transistor, named in the Japanese 2SD series and companion in numbering to the neighbouring 2SD1800 sheet.

The 2SD1724 part number is all the name gives, and the 145 KB PDF is tagged as a schematic, though a file named this way is normally a transistor datasheet.

Labelled 2SD2526, this 192 KB PDF contains reference data for a Japanese-coded transistor rather than a device-level circuit.

Small 40.1 KB PDF for the 2SD1957, written in lower case in the original name and catalogued under schematics.

The 2SK2843 is the only detail in this file name, an N-channel FET designation under the Japanese JIS scheme.

Datasheet PDF of 114 KB for the 2SK2616, a part named under the Japanese JIS scheme for N-channel field-effect transistors.

Short PDF of 30.9 KB for the 2SK2538, with the part number written in lowercase in the original name.

Covering the 2SK2507, this 422 KB PDF belongs to the JIS family of N-channel field-effect transistors denoted by the 2SK prefix.

Short 36.3 KB PDF on the 2SK1803. Part numbers prefixed 2SK are N-channel field-effect transistors in the Japanese JIS registration system, and this file is most likely…

Datasheet PDF for the 2SK1771, about 305 KB in size. Under JIS conventions, the 2SK prefix identifies an N-channel FET; the file is listed as a schematic but the name…

Datasheet PDF for the 2SK1472 N-channel field-effect transistor, inferred from the Japanese 2SK designation, though the catalogue files it under schematics.

Listed as a schematic, this 105 KB PDF is named only after the 2SK1430 transistor and is probably its datasheet.

PDF sheet for the 2SK1381 transistor, an N-channel FET in the Japanese 2SK series, about 443 KB in size, which suggests full characteristic graphs and mechanical data.
