Unlabeled 16.0 MB BIOS binary called 0883C, a name that looks like a hexadecimal system or board ID but states no model or brand.

Schematic archive named only M33, with no brand given, a 940 KB ZIP. The name is too brief to identify the device reliably; it may be a phone model code, but that is not…

Archive named MB Images, 87.4 MB in RAR format; the name does not identify a device, board or brand.

PDF document of 132 KB for the HCF4093, the ST version of the 4093 quad two-input NAND gate with Schmitt-trigger inputs.

PDF reference for the 2SD1852, a 2SD-series NPN bipolar transistor, about 96.5 KB and more likely a component datasheet than a circuit diagram.

Data for the 2SD2184, an NPN low-frequency bipolar transistor according to the Japanese 2SD numbering prefix, supplied as a 43.8 KB PDF.

Part documentation for the 2SD2579, provided as a PDF of 43.3 KB under the schematic heading.

Datasheet-style document, 133 KB in PDF format, covering the 2SD1681 part number and listed as a schematic.

Covering the 2SD2067, this 60 KB PDF carries an E suffix that the name leaves unexplained.

Larger 185 KB PDF for the 2SD2012, written in lowercase in the name and placed among schematics.

Very small 22.2 KB PDF relating to the 2SD1999, filed as a schematic. The name offers nothing but the part code, which follows the JIS scheme where 2SD denotes an NPN…

An 88.2 KB PDF titled 2SD1884, indexed in the schematic section but, judging by the bare part number, a datasheet for that transistor.

A 30.6 KB PDF for the 2SK3278, indexed as a schematic but holding component reference data.

Part datasheet, most likely, for the 2SK2837, provided as a 426 KB PDF and indexed as a schematic.

A 429 KB PDF titled 2SK2789 and stored among schematics, most likely the datasheet for that part.

Component datasheet for the 2SK2661, a 385 KB PDF that is indexed as a schematic. Under JIS naming, the 2SK prefix marks an N-channel field-effect transistor, so look…

Small 23.4 KB PDF for the 2SK2660 transistor. The 2SK designation comes from the Japanese JIS system for N-channel FETs, so the file is most likely a brief datasheet…

Part documentation for the 2SK2628LS, a 28.6 KB PDF. The 2SK prefix places it in the Japanese JIS family of N-channel field-effect transistors, and the LS suffix denotes…

PDF reference document of 413 KB for the 2SK2508 transistor, filed as a schematic. In JIS naming the 2SK prefix identifies an N-channel field-effect transistor; the name…

The 2SK2445 gives its name to this 410 KB PDF, categorised as a schematic yet most likely a datasheet, because 2SK codes in the JIS scheme identify N-channel FETs.

The part number 2sk2210 is the sole clue to this 33.6 KB PDF, catalogued under schematics but most likely a short component datasheet.

The 2SK2171 referenced in this 180 KB PDF is an N-channel field-effect transistor by JIS/EIAJ convention, which uses the 2SK prefix for that class.

The 2SK2129, a JIS-registered N-channel FET, is the only thing the name identifies in this 32 KB PDF.

PDF of 98.9 KB for the 2SK1898, listed under schematics but in practice a component reference for one transistor.

Only the part number 2SK1897 identifies this 97.1 KB PDF, which the index places among schematics.

PDF reference, 105 KB, for the 2SK1813 transistor. In the Japanese JIS scheme, 2SK designates an N-channel field-effect transistor, so this is probably its datasheet.

A 105 KB PDF for component 2SK1432, categorised as a schematic though the name identifies only a single transistor.

For the 2SK1427 N-channel FET, this 101 KB PDF sits in the schematic section of the index but most likely contains a datasheet.

PDF sheet for the 2SK1233 MOSFET, size 46.1 KB, part of the Japanese 2SK series of N-channel field-effect transistors.
