The 2SC4108 is the only detail this 94 KB PDF name provides, and the index files it as a schematic.

Concerning the 2SC5452, this 42.4 KB PDF is listed as a schematic but, judging by size and part number, is a component datasheet for an NPN transistor in the Japanese…

Around 173 KB of PDF datasheet material for the 2SC5307, an NPN bipolar transistor in the Japanese JIS 2SC series. The name gives no maker, package or intended circuit.

Short PDF of 21.2 KB covering the 2SA1575, probably a brief part datasheet despite the schematic label. The name contains no device or manufacturer information.

PDF reference for the 2SA1968, 91.3 KB, indexed as a schematic though the bare part-number name points to a transistor datasheet.

Datasheet-style PDF of 41.8 KB covering the 2SA1790, a JIS-coded PNP bipolar transistor, placed in the schematic section of the catalogue.

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.

Largest sheet in this group at 469 KB, this PDF for the 2N5962 is listed as a schematic, though it is likely a detailed datasheet with graphs.

At 495 KB this PDF, named 93lc56, is larger than the other 93-series files and probably a full datasheet for that Microwire serial EEPROM, despite the schematic label.

A 638 KB PDF named 16M-DRAM, filed as a schematic. The name indicates a 16-megabit DRAM device or document but gives no manufacturer, part number, board or revision, so…
