MSI EX600 notebook schematic, board MS-1636 revision 1.1, in a 1.10 MB PDF. MSI designs its own laptop boards, and MS-16xx codes identify the mainboard; check that the…

BA1404 reference PDF, 140 KB, for the ROHM FM stereo transmitter IC often used in small hobby and consumer FM transmitter circuits.

Transistor datasheet for the 2SD2155, stored as a 177 KB PDF and filed with schematics.

Compact 25.2 KB PDF named for the 3SK301, categorised as a schematic but most likely a part datasheet. Nothing besides the type number appears in the name.

Reference sheet for the 2SK2844 transistor, stored as a 427 KB PDF and catalogued under schematics.

Although stored as a schematic, this 409 KB file named 2SK2173 most likely contains a component datasheet.

Datasheet-type PDF for the 2SK2103, about 128 KB, listed under schematics. Under the JIS scheme the 2SK prefix denotes an N-channel field-effect transistor.

An 86.9 KB PDF identified by the part number 2SJ231 alone. Under Japanese JIS designation, 2SJ covers P-channel FETs, so this is most plausibly a transistor datasheet…

Component sheet for the 2SD1191, delivered as a 143 KB PDF and categorised as a schematic, though the name suggests a datasheet for a single part.

Covering the 2SD1134 transistor, this 43.0 KB PDF sits in the schematic category, yet its name is a bare part number typical of a datasheet.

A 144 KB PDF specification for the 2SC4481 transistor, filed as a schematic but in fact a component datasheet.

Datasheet for the 2SC4480, stored as a 99.8 KB PDF that opens in any standard reader. By JIS convention the 2SC prefix denotes an NPN bipolar transistor; the name gives…

At 188 KB, this PDF for the 2SC5466 is larger than a basic sheet and likely includes full characteristic curves and package drawings.

The 2SC4944 is the only detail carried by this 259 KB PDF, catalogued as a schematic. Since 2SC is the JIS/JEITA prefix for NPN bipolar transistors, the document should…

For the 2SC3326, this 281 KB PDF is filed as a schematic although its title points to a component datasheet.

Labelled 2SC2405_E, this 54 KB PDF is associated with the 2SC2405 NPN transistor. The 2SC prefix follows the JIS naming standard, and the _E suffix is not explained by…

Reference PDF for the 2SA1923 transistor, 195 KB, catalogued as a schematic though nothing in the name beyond the part number indicates more than a datasheet.

PDF datasheet, 178 KB, for the 2SA1804 transistor. In Japanese JIS numbering a 2SA part is a PNP bipolar transistor, and this document should provide its voltage…

A 200 KB PDF on the 2N3905, distinguished by an RE suffix that the name leaves unexplained, possibly an alternate or revised vendor edition.

Carrying only the code 112cnq030a, this 193 KB PDF is catalogued as a schematic yet mentions no laptop, board number or revision.

The 223 KB PDF called 93lc46 refers to a small Microwire serial EEPROM and is likely the datasheet rather than a board schematic.

Archive titled only 16mb, giving no hint about the device, brand or board it belongs to.

CQ56 firmware image, 2.00 MB and without extension, whose name reads cq56iorigi, most likely an original dump of an Intel-based CQ56.

Brief PDF of about 60 KB documenting the PG320240-D display module, one of the lettered variants of a 320 x 240 dot graphic LCD series.

Datasheet for the Sitronix ST7565S, a controller and driver for small monochrome graphic dot-matrix LCDs, in a 715 KB PDF.

Dahua DH-XVR4B08H recorder archive, 158 MB in ZIP form, tagged D1820 and 41_208, apparently the PCB code and board version.

Schematic for MSI motherboard MS-16811 at revision 0B, provided as a PDF inside an 826 KB RAR archive.

Copy of the TH50PV80D plasma television schematic marked with a -1 suffix, 10 MB in PDF, the same size as the unsuffixed file and likely a duplicate.

Schematic PDF for the TH65PX600U television, about 34.7 MB, a size that suggests a full service manual rather than a single page.

BIOS dump for an HP G62-220us notebook with an Intel Pentium processor, supplied without a file extension.

Another 2.43 MB copy named 3CESV-RH-01, matching an entry with the same name and size, so it is probably a duplicate.

Schematic PDF with a short name showing only JV50, a MV tag, -1 and 0109, which is likely a project code with a revision and date, though the brand and model are not…

Datasheet PDF of 3.36 MB covering the mega16, mega32 and mega64 M1 variants, matching the Atmel AVR ATmega16M1/32M1/64M1 family aimed at automotive and motor control use…
