Raw 32.0 MB read of the flash chip at board position U367; the name gives only the reference designator, with no device or board.

Firmware for the SR-8989HD Premier receiver, version 3.95, dated in the name and tagged MultSW, which likely indicates a multi-software build.

Firmware archive named after the W25Q64BV, a Winbond 64 Mbit (8 MB) SPI flash chip, followed by a date-like code 20210730; no device or board is stated.

PDF document titled DBL2018-C, 233 KB, catalogued as a schematic. The name offers only a part or document code with a C suffix and does not identify the device or maker…

Datasheet for a part marked D304X, provided as a 924 KB PDF. The file name gives no description of the component category or manufacturer, so the document itself must be…

Small 67.8 KB PDF for the 2SD1854, a part number in the Japanese 2SD series of NPN bipolar transistors, so it is really a datasheet rather than a full schematic.

Datasheet for the 2SD2258 NPN bipolar transistor, supplied as a 56.8 KB PDF and filed under schematics.

Component reference for the 2SD2635, a 35.2 KB PDF listed among schematics. The file name offers only the part number, with no manufacturer or revision given.
