Info: This service guide and parts catalog documents the CANON: SX-3010 Memory Box, an external expansion unit for the CANON: SX300 programmable calculator.
It explains how the unit adds program and data memory and provides the diagrams, diagnostic program, and parts references needed for servicing.
Memory expansion:
The guide shows how the memory cards are assigned to program or data pages.
The same card can serve either purpose without modification.
Circuit diagrams:
A block diagram traces signals between the calculator and the Memory Box.
Separate schematics cover the control card, memory cards, motherboard wiring, and power supply.
Diagnostics:
A complete test program checks a selected range of data-memory addresses.
The printout confirms a successful test or lists faulty addresses and the values read from them. Program-memory cards can be checked by moving them into data-memory slots.
Parts identification:
An exploded view and numbered parts tables identify circuit assemblies, enclosure pieces, connectors, and individual components.
