Raw 32.0 MB dump read from the chip at board position U366. The name records only that designator, so the device, brand and board revision cannot be identified from it.

Small 27.3 KB PDF for part 5LN02C, listed as a schematic though it is evidently a discrete-device datasheet.

Datasheet for the 5LN01SP in PDF format, roughly 28.0 KB, indexed as a schematic. Only the part number is stated; LN in this series appears to denote an N-channel…

Compact 27 KB PDF named 5HP01M, catalogued as a schematic but pointing to a single semiconductor component.

Datasheet-style PDF for the 3SK264, roughly 82.2 KB, indexed as a schematic. The name contains only the type number.

A 295 KB PDF on the 2SK1825 semiconductor. The 2SK prefix follows the JIS standard for N-channel FETs, suggesting a datasheet despite the schematic category.

Datasheet PDF for the 2SK1472 N-channel field-effect transistor, inferred from the Japanese 2SK designation, though the catalogue files it under schematics.

Compact 90.8 KB PDF identified only by the code 2SK1469. In Japanese semiconductor numbering, 2SK stands for an N-channel FET, so the schematic tag aside, this should be…

PDF sheet for the 2SK1381 transistor, an N-channel FET in the Japanese 2SK series, about 443 KB in size, which suggests full characteristic graphs and mechanical data.

At 414 KB this is one of the larger PDFs in the 2SJ series, covering the 2SJ334. Only the part number appears in the name.

A 136 KB PDF for the 2SC4616, listed among schematics though the name only carries a component part number, implying a transistor datasheet.

2SC5154 is the only detail in this 198 KB PDF name, and that JIS designation points to an NPN bipolar transistor of the high-frequency group, so treat the file as a…

The name of this 150 KB PDF gives only 2SC4409, a JIS-style part number where 2SC stands for an NPN bipolar transistor.

Datasheet PDF of 42.3 KB for the 2SC5638, listed in the schematics section though the name refers to one transistor.

At 214 KB, the 2SC3964 PDF is one of the larger files in this group, likely a full datasheet with characteristic curves for this JIS-numbered NPN bipolar transistor…

An NPN transistor reference for the 2SC3897, supplied as a 93.9 KB PDF. Part numbers with the 2SC prefix follow the Japanese JIS scheme for NPN bipolar devices, so this…

Reference sheet for the 2SC3619 transistor, stored as a 214 KB PDF and catalogued with schematics.

Datasheet for the 2SB1381 transistor, supplied as a 223 KB PDF and catalogued under schematics. The file name contains only the part number.

Covering the 2SA1242, this 212 KB PDF carries only the part number in its name, so it is best treated as the component datasheet despite the schematic label.

For the 2SA1213 there is this 224 KB PDF, categorised as a schematic, though the part-number-only name points to a component datasheet.

Part datasheet in PDF form, 172 KB, for the 2SA949, listed in the schematic category of the index.

A 146 KB PDF with the JEDEC part number 2N6766 as its only identifier, catalogued as a schematic. Nothing in the name ties it to a particular device or board revision.
