For technicians handling the 2SA1749, this 128 KB PDF provides the datasheet for a PNP bipolar transistor, as the JIS 2SA prefix signifies, even though the catalogue…

English-edition style datasheet, judging by the _E suffix common to Japanese maker documents, for the 2SA1748 PNP bipolar transistor; 39.5 KB PDF, filed as a schematic.

A 149 KB PDF for the 2N6107, catalogued as a schematic though almost certainly a datasheet, carrying an RE suffix whose meaning is not stated.

A 209 KB PDF for the 2N6055, carrying an unexplained RE suffix that may indicate a revised edition.

The 2N5087 is the only detail in the name of this 100 KB PDF, catalogued as a schematic but most likely a part datasheet.

Only the series code 81CNQ appears in the name of this 125 KB PDF, suggesting a family datasheet covering several voltage grades of dual Schottky rectifiers in…

Indexed under schematics, this 126 KB PDF is named 300CNQ035 and states no device, manufacturer or board revision.

Schematic PDF, 2.09 MB, named only T61. The name states no brand, board number or revision, so read the document cover to confirm what board it describes.

RAR archive called 08BAD, 7.30 MB in size, whose name reveals nothing reliable about the device, board number or contents.

Raw 8.00 MB BIOS dump read from a GigaDevice GD25Q64 64 Mbit SPI chip on 10 May 2018, labelled kampinswd, which reveals no laptop brand, model or board number.

Schematic in PDF for the Quanta Y0J platform, motherboard DA0Y0JMB6D0, carrying the 0817A date or revision tag in its name.

A 122 KB PDF datasheet named SDZS003A, a literature number whose final letter usually indicates a document revision.

ROM file called amiboot, 512 KB, whose name hints at an AMI BIOS image but gives no board, model or version. The 4 Mbit size suggests an older desktop or embedded board.

Large ZIP archive of 362 MB named Sibelius, which is also the name of a well-known music notation application.

Mainboard archive for 6050A2547701, revision MB-A02, labelled with the project code 15SBGU.
