File:Sinclair ZX Spectrum Issue 6A DC-DC converter circuit.png
Summary
[edit | edit source]
Crop of Sinclair's ZX Spectrum Issue 6A circuit diagram showing the DC-DC converter with Sinclair's final modification built in (C80, D17, D18, C79, R79 and the BZY88 zener D19). The larger "560pF" label and the line pointing to C49 are an annotation added to this copy of the drawing, not part of Sinclair's original. Cropped at full resolution for Sinclair ZX Spectrum DC-DC Converter Repair.
