Indexed as a schematic, this 50.3 KB PDF is titled 1N757A, a JEDEC 1N diode number with A suffix, so it almost certainly holds a part datasheet.

Filed as a schematic, the 209CNQ135 document is almost certainly a datasheet for a high-current Schottky rectifier module in the CNQ series, where 135 points to a 135 V…

Filed as a schematic, this 161 KB PDF titled 27lc010 is almost certainly a component datasheet rather than a board diagram.

Raw BIOS dump labelled G6A, 2.00 MB in size, suited to a 16 Mbit flash chip. Nothing in the name gives a brand, motherboard number or revision, and the letter A is not…

BIOS / firmware archive labelled 08BE5 DMI, packed as RAR at 7.56 MB. The name does not give a brand, model or board number, and 08BE5 may be a board or system…

Dahua DHI-XVR4116HS-S2 recorder archive, 14.9 MB ZIP, with codes 21_738, D1722 and 80176869 identifying board version, PCB and part number.

Archive labelled for the Dell OptiPlex 790, but only 160 bytes in size, far too small to hold a BIOS image, so it is almost certainly empty, a placeholder, or a broken…

Quanta ED2 motherboard schematic, UMA edition, version 1C and revision C2A, provided as a roughly 1007 KB PDF.

PDF schematic for the ASUS X409 series, with the name listing the X409FA, X409FB, X409FJ and X409FL variants that share this design.

Firmware dump for an ETON ET856 board, RAR of about 3.96 MB. The other tokens, 94V-0 and E213441, are PCB flammability and UL certification markings rather than a model…

Compact 130 KB RAR archive named C5225 T, a name too terse to identify the device, brand or document type with certainty.

ZIP archive for the ASUS X550CA and X550CC, mainboard R2.0, centred on disabling the onboard RAM.

Schematic for the Apple iPad 2 logic board, saved as a 637 KB PDF. Repair technicians use such drawings to trace supply rails, check the charging and battery circuits…

RAR archive of 1.30 MB for the ASUS A6KM, tagged R10 and 080205. R10 likely means revision 1.0 and 080205 looks like a date code, but neither is certain from the name…

Compal LS-8481P schematic in a 52.9 KB RAR archive. Unlike its siblings, the name states no revision, and no laptop model is mentioned either.

Firmware for a Dell 5050 machine, marked dv15 MLK MB in the name, in a 3.09 MB RAR archive.

PDF schematic for the Lenovo ThinkPad W700 DDR3 variant, about 2.21 MB, with an added note in the name reading N-note 07247 4Y90 whose meaning is not certain; it may be…

BIOS archive for an ASUS K42JA laptop, where the trailing M213 appears to be a version tag, though only K42JA is certain from the name.

Datasheet for the LM45, an analog Celsius temperature sensor whose output voltage rises linearly with temperature, at about 10 mV per degree.

Named for the 2SK2824 transistor, this 305 KB PDF is indexed as a schematic but is most likely a single-part datasheet.

A 418 KB PDF named for the 2SK2742, an N-channel field-effect transistor under the Japanese JIS 2SK prefix, placed in the schematic category.

A 134 KB PDF for the 2SK2460N, catalogued as a schematic but almost certainly a datasheet for a discrete transistor, since 2SK numbers under the Japanese JIS system…

Reference sheet for the 2SK1529, a part number that follows the Japanese 2SK scheme used for N-channel FETs.

Part number 2SC4324 is the only information in the name of this 468 KB PDF, which is catalogued as a schematic but almost certainly holds the device datasheet.

At 108 KB, this PDF is labelled with the transistor type 2SC4221 and nothing else, so no board, model or revision is identified.

Part number 2SC4124 names this 98.7 KB PDF, which is labelled a schematic but, given the JIS-style designation for an NPN bipolar transistor, should be that part's…

A small 28.7 KB PDF identified only by the code 2SC5680, a number of the Japanese 2SC family of NPN bipolar transistors.

PDF sheet for the 2SC3935 part, with an _E suffix after the number, filed under schematics at 40.7 KB.

Data for the 2SC3122 transistor in a 268 KB PDF, listed under the schematic type. Following JIS numbering, the 2SC prefix marks an NPN bipolar device, and the case often…

Part number 2SC2882 names this 137 KB PDF, which the index treats as a schematic. The 2SC prefix in the JIS system indicates an NPN bipolar transistor, making a…

Named for the 2SB1214 transistor, this 71.3 KB PDF is catalogued as a schematic but is expected to be the part's datasheet.

Reference PDF for the 2SB789 transistor, 42.5 KB in size. Under JIS naming, the 2SB prefix denotes a PNP transistor aimed at low-frequency use, and a file named only by…

The 2SB767 is covered by this 42.9 KB PDF, whose name adds only an _E suffix that cannot be decoded from the name alone.

PNP transistor documentation for the 2SA1150, provided as a 193 KB PDF. JIS naming uses 2SA for PNP bipolar devices, so although indexed as a schematic the file almost…

A compact 50 KB PDF named after the JEDEC-registered part 2N720A, indexed under schematics but almost certainly a component datasheet rather than a board drawing.

Part 83CNQ080A is the subject of this 207 KB PDF, indexed as a schematic but almost certainly a component datasheet, since the code follows the International Rectifier…

The 24WC257 is a Catalyst Semiconductor I2C serial EEPROM, and this 55.6 KB PDF, though catalogued as a schematic, is almost certainly its datasheet.

Windows software package for the CSTXE System Tool, version 4.0.5.1280, in a 4.86 MB RAR archive.

Second copy of the 630IG firmware, a 4.00 MB .bin image lacking brand, board number and version in its name.

Generic 8 MB binary called main, a name that tells nothing about the laptop, board or chip.
