Toshiba BIOS for a board marked UMT-SZ 2MV, with the flash chip identified as an EN25F32, a 32 Mbit device giving 4MB capacity.

PDF document of 275 KB for the 2N5883, with an RE suffix the name does not explain, possibly a revision marker.

Combined datasheet for the Microchip PIC16F7x series of flash microcontrollers, provided as a 3.95 MB PDF.

Named after the 2SK210, this 362 KB PDF sits in the schematic category but most probably contains the datasheet for that JIS N-channel FET.

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

RAR archive of 5.48 MB named only SM, which gives no model, board number or file type. The prefix resembles Samsung model codes, but the actual device cannot be…

A 34 KB PDF linked to the 2SK2123, listed as a schematic but probably the device's datasheet.

PDF data sheet, about 135 KB, covering the 2SC4540 transistor. Under JIS semiconductor numbering the 2SC prefix identifies an NPN bipolar device, so the document should…

The 2N6849 datasheet, a 133 KB PDF filed as a schematic. Its file size and number sit close to the neighbouring 2N6845, 2N6847 and 2N6851 sheets, hinting at a family of…

ZIP archive of 18.5 MB named UnlockTool Pro, a software utility rather than a board firmware dump, despite its BIOS category.

PDF of 1.44 MB named HT7166, catalogued under schematics, with no device, brand or board stated in the name.

Firmware archive for the PLANET ADW-4401 modem, a network device rather than a laptop. The name gives no version or chip details, so check what the archive holds before…

Part list PDF, 52.1 KB, whose generic name gives no device, brand or board number. A parts list maps location designators to part numbers, values and descriptions…

Small 334 KB PDF schematic identified only as qm3016d, with no brand or device named in the file name.

Large 9.17 MB PDF datasheet from Microchip for the PIC18Cxx8 family, EPROM/OTP microcontrollers in the PIC18 line that include a CAN bus module.

Small RAR archive of 754 KB named only SX, which says little about the device it belongs to.

A 121 KB PDF named 2SK2170, listed among schematics but most likely the datasheet for that single device.

The 2sa2005 file is a 51.5 KB PDF named for a JIS-designated PNP bipolar transistor, 2SA being the prefix for that device class.

A 40.2 MB zip archive named TunaPro, which gives no device model, board number or file contents.

Texas Instruments literature number SDLS135, supplied as a 289 KB PDF datasheet. The name carries no part number, so the covered logic device has to be confirmed from…

Datasheet-style PDF named after the part code 5HP02N, about 41 KB in size and filed with schematics.

A 94.8 KB PDF documenting the 2SD895, indexed as a schematic though the name names a single transistor.

PDF of 137 KB identified only by the part number 2SC2782, filed with schematics but almost certainly a transistor datasheet.

A 121 KB PDF for the 2N6027, filed as a schematic but most likely the device datasheet. The name gives no manufacturer, package or revision.

Large 44.5 MB PDF catalogued as a schematic, its Persian file name roughly meaning mobile repairer.

2.1 amplifier schematic attributed to Amiru, a compact 98.7 KB PDF. The name gives no details about the ICs or power level, so the diagram itself must be read for…

A 200 KB PDF for the 2SC5458, a part in the Japanese 2SC numbering scheme for NPN bipolar transistors, filed here as a schematic.

Datasheet PDF, 40.9 KB, for the 2SA1128 transistor, with an _E suffix that often denotes an English edition of Japanese documentation, though the name does not confirm…

Part-number PDF, 132 KB, for the JEDEC-registered device 2N6798, listed in the schematic category.

Filed as a schematic, this 145 KB PDF is named only 2N6770, a JEDEC-registered semiconductor number. No host device or board is mentioned.

A 1.17 MB PDF datasheet for the Microchip PIC16F6xx flash microcontrollers, with the name indicating a family placeholder rather than a single part number.

Programmer read file from a Macronix MX25L12835F chip, labelled Bios2 and merged, with a 48 MB .bin size.

Component sheet covering the 3N254, delivered as a 42.2 KB PDF and indexed as a schematic. JEDEC numbers beginning with 3N denote registered devices having four leads.

PDF for the 2SK1053 transistor, 107 KB, filed as a schematic but by its name a single-part datasheet.

Reference sheet for the 2SA1814 transistor, supplied as an 84.8 KB PDF. The 2SA designation in Japanese JIS numbering means a PNP bipolar device, so the document should…

A 708 KB PDF indexed under schematics and named only with the part number 2N5771, with no board, revision or device given.
