What this document does not contain
[edit | edit source]- No component values beyond the parts list, and no power supply circuit diagram in the list of drawings.
- The circuit diagrams at the end of the scan are image-only, so they cannot be searched, and at 150 dpi on A4 many values are hard to read. The same drawings at 300 dpi are on BBC Master Series Documentation.
