Firmware dump for a board marked DAC_BC rev 1A and DAC_BC05 rev A1, with a 19A2BC0503 code and an SST25VF080B flash chip named, dated 2018-06-05.

Datasheet for the BC557 small-signal PNP transistor, a 45.8 KB PDF that matches the size of the other BC557 files in this collection.

Datasheet for the BC328 PNP transistor in PDF format, 53.5 KB, the same size as the combined BC327 and BC328 sheet in this index.

Datasheet for the BC338 NPN transistor, a compact 29.8 KB PDF matching the BC337 sheet in size and probably the same family document.

Combined datasheet for the BC327 and BC328 PNP transistors, a 53.5 KB PDF. The two types share package and gain grouping and differ mainly in collector-emitter voltage…

Windows executable named BCU, 8.80 MB. On HP systems BCU usually refers to the BIOS Configuration Utility, a command-line tool for reading and changing BIOS settings…

Data sheet for the BC337 NPN general-purpose transistor, 29.8 KB PDF. It should give pinout, outline dimensions, absolute maximum ratings, gain classes and switching…

PDF data for the BC328 PNP transistor, the name listing minus 30 V and minus 800 mA ratings, filed under schematics at 53.5 KB.

General datasheet for the BC548 NPN small-signal transistor, 32.8 KB in PDF format and apparently matching the BC548B document in size.

PDF schematic labelled BCi with the year 2012, most likely an amplifier design from the same family as other BCi drawings, though the name itself states no power rating…

Combined datasheet for the BC546 and BC547 NPN small-signal transistors, packaged as a 57.5 KB PDF.

Data sheet for the BC237 NPN small-signal transistor, supplied as a 54.8 KB PDF. It should include package outline, terminal arrangement, maximum ratings, gain groups…
