What this document does not contain
[edit | edit source]- A parts list or a complete schematic. The circuit appears as separate figures, one per block.
- Component values for anything not drawn in those figures.
- Disassembly, adjustment or mechanical service procedures.
- The test fixture itself or its program.
The text on page 2 says the +15 V supply feeds the reset circuit and Z200; the figures on pages 3 and 4 show both on +5 V.
