BIOS ROM for the Acer Aspire 5930 with a Duo-class processor on an Intel Mobile 4 Series chipset.

Power sequence document for the ASUS ROG GU603, an 882 KB PDF classed as a schematic. A sequence chart shows the order in which rails and enable or power-good signals…

The 232 KB PDF covers the 2SD1947A, a JIS NPN transistor number with an A suffix that the name states.

Identified solely as 2SJ257, this 96.0 KB PDF most likely documents a P-channel FET, the device class assigned the 2SJ prefix in the JIS system.

Filed as a schematic, this 120 KB PDF is named only after the part number 2SC4402, so it is most likely the manufacturer datasheet for that transistor rather than a…

The 2SC5588 is covered by this 332 KB PDF document. Apart from the part number the name gives no detail, so maker and revision are unknown until the file is opened.

A 98.4 KB PDF titled with the part number 2SC4162, filed under schematics but in practice expected to be the datasheet for that transistor.

A small 37.1 KB PDF named in lowercase after the 2SC4137, labelled as a schematic but most plausibly a concise datasheet for that part.

Small 40.7 KB PDF named 2SC2925 with an added _E suffix, classified here as a schematic.

Compact 57.8 KB PDF named after the 2SC2206, with an _E suffix in the file name whose meaning is not stated.

Although catalogued as a schematic, this 51.4 KB PDF is named for the 2SC1317, which the JIS 2SC prefix identifies as an NPN bipolar transistor, so a component datasheet…

An 80.4 KB PDF covering the 2sb1260 transistor, listed in the index under schematics. No maker, package or device model is given in the name.

PDF of about 228 KB for the 2SA1297 PNP transistor, the 2SA prefix being the Japanese JIS designation for that device class.

Reference sheet for the 2SA1244 transistor in PDF form, 295 KB, listed as a schematic even though the name gives nothing beyond the part number and the file is most…

At 377 KB this is the largest of a group of PDFs named after 1N part codes; this one is 1N1183, a JEDEC style diode designation, so it is most probably a datasheet even…

Labelled only 241NQ, this 45.4 KB-class PDF of 45.2 KB appears to be a series datasheet for a family of power rectifier devices, with no suffix pinning it to a single…

Specification document, version 1.0, for the PD064VT5N1 display panel, packaged as a 494 KB PDF. The 064 group suggests a 6.4 inch class TFT.

ZIP archive with Intel Server Platform Services firmware, version 06.00.03.604, about 1.81 MB.

Firmware package for the X53E-SX1556D in its version without a discrete GPU, compressed into a 1.42 MB-class RAR of 1.47 MB.

Service schematics for the ASUS VW198T LCD monitor, stored in a 3.77 MB-class 3.71 MB RAR archive. The model is the only detail in the name.

PCWARE IPM31 motherboard firmware, revision 1.03, supplied as a 424 KB RAR. The IPM31 name points to an Intel G31-class desktop board, although the chipset is not…

256-byte dump associated with an i1501 and a B154EW01 V4 LCD panel, most likely the EDID data stored in the screen EEPROM.

Small Portuguese PDF of 57.8 KB that, judging by its name, is a May schedule for live classes rather than a circuit diagram, despite being filed under schematics and…

Schematic service manual for the Haier HL22XLT2 and HL22XLTW2 22-inch-class LCD TVs, supplied as a 5.77 MB PDF.

SPI flash dump for the Samsung UA23H4003AR television, taken from a Winbond W25Q32 chip; the 4 MB file matches that 32 Mbit capacity.
