File:Aquarius Mini Expander v1-1-0 Rev C Schematic.pdf
Summary
[edit | edit source]Schematic of the Aquarius Mini Expander v1-1-0 Rev C (14 February 2021), Sean P. Harrington's redrawing and recreation of the Mattel Aquarius Mini Expander. One A2 sheet: board edge connector to the Aquarius, 74LS244 address buffers, address decoding (74LS04, 74LS02, 74LS30, 74LS74), the AY-3-8910 sound and I/O chip, the two control pad connectors, the sound mixing transistor, the front and rear card edge ports, and the supply filter (L1 33 µH with C8 10 µF and ceramic capacitors). Harrington's README says the original Radofin schematic was used to check it and that minor discrepancies were corrected from the actual board.
