Learning document about the function generator and oscilloscope, provided as a 662 KB PDF. It is not a board schematic but material on two core bench instruments.

A 146 KB PDF labelled 93LC76, which follows the naming of Microwire serial EEPROMs, so it is probably the datasheet for that device even though catalogued as a…

PDF of 674 KB named 25C01, catalogued among schematics, with no manufacturer, laptop or board identified.

Titled for the 93LC46, 56 and 66, this 223 KB PDF is a combined datasheet for three densities of Microwire serial EEPROM, although indexed as a schematic.

PDF of 536 KB for the Atmel AT93C46, a small serial EEPROM using the Microwire-style three-wire interface.

Combined datasheet in PDF covering the 93C06 and 93C46 serial EEPROMs, small low-density Microwire memories from the 93-series family, 135 KB in size.

Datasheet of 243 KB in PDF for the 93C46B, a 1 Kbit serial EEPROM of the 93-series Microwire family; the B suffix generally identifies a version with fixed word…

Bematech BR-310 manual in PDF format, 443 KB, for a model in the Bematech BR line of barcode scanners used at retail checkouts.

Here is a 323 KB PDF named for the 25AA040, 25LC040 and 25C040, a Microchip family of 4 Kbit SPI serial EEPROMs; despite the schematic label it is a datasheet.

Complete-looking datasheet PDF of 675 KB named 25C02, catalogued as a schematic. By standard naming it covers a 2 Kbit SPI serial EEPROM, without any manufacturer…

Named 93CXX and sized at 132 KB, this PDF is listed as a schematic but appears to be a generic datasheet for 93C-series Microwire serial EEPROMs.

Data sheet for the 1T362 transistor, 45.0 KB in PDF, stored in the schematic category. The 1T prefix belongs to the old Soviet numbering, denoting a germanium transistor…

Maintenance manual in PDF for the Huawei MediaPad 10 FHD tablet, filed here under schematics.

Datasheet-style PDF for the BQ24726, a Texas Instruments SMBus charge controller part number used in notebook power circuits, size 1.28 MB.

Spanish-language section 3.3 on the oscilloscope, part of a workshop equipment chapter in a phone repair course, supplied as a 362 KB PDF.

PDF document of 577 KB for the AD620, filed in the schematic category although a part-number name like this normally indicates a component datasheet.

PDF of 99.2 KB titled 25C64-128 and stored with schematics, apparently covering 25-series SPI serial EEPROMs in 64 and 128 Kbit densities.

Covering the 25AA320, 25LC320 and 25C320, this 383 KB PDF is listed as a schematic but is in practice the datasheet for a Microchip family of 32 Kbit SPI serial EEPROMs.

Topic 3 of a Spanish mobile repair course, giving an overview of workshop equipment in a 1.00 MB PDF. It is not tied to any device.
