Compact 31.4 KB PDF datasheet for a 1N4001 variant marked ID in the name, catalogued in the schematic section.

Indexed as a schematic, this 50.3 KB PDF is titled 1N757A, a JEDEC 1N diode number with A suffix, so it almost certainly holds a part datasheet.

A 126 KB PDF catalogued as a schematic and labelled 5THZ52, without any device, board number or revision.

This 194 KB PDF is labelled simply 113cnq and filed as a schematic, with no device, board number or revision in the name.

Titled simply 111ria, this 104 KB PDF is indexed as a schematic, though the name resembles a power semiconductor series code rather than a motherboard identifier.

A 88.2 KB PDF catalogued as a schematic, its name covering a range from 1SMA5.0AT3 to 78AT3, a naming pattern associated with unidirectional transient voltage suppressor…

PDF datasheet for the 93C46CB, a variant of the 93C46 1 Kbit Microwire serial EEPROM, the smallest and most common member of the 93-series family.

Filed among schematics, this 91.7 KB PDF is named 2764 with nothing else to identify brand or board.

A 240 KB PDF whose short name, 42vforisa, gives little away; it seems to reference a 42 V specification, possibly related to an ISA bus or a part family, but that cannot…

PDF of 164 KB catalogued as a schematic and named 28F020 with a trailing underscore, which usually marks an alternate copy of the same part document, possibly from a…

Labelled 27c4096, this 111 KB PDF sits in the schematic section but the name is a part number from the 27C CMOS EPROM series.

A 135 KB PDF for the part 27c512, placed in the schematic category but in practice a datasheet for a member of the widely used 27C CMOS EPROM family.

PDF of 119 KB named 27C256B, filed as a schematic yet clearly a part number from the 27C CMOS EPROM line, here with a B revision letter.

A 171 KB PDF named 27c010, categorised as a schematic, though the number marks it as a part from the 27C CMOS EPROM line. No device, brand or board appears in the name.

The short name 12tq on this 179 KB PDF suggests a family-level datasheet for Schottky rectifiers in the International Rectifier or Vishay style, covering several voltage…
