Models that take it

• Logitech GROUP extension cable: No safe generic. Doesn't apply
• Commodore 64: Cheaper aftermarket part. 5V DC, 1.5A min (1.7A for C64C) plus 9V AC, 1A, 7-pin DIN. AC output on one line Check first: Check it says 5V DC and 9V AC with a round 7-pin DIN, and measure both outputs before plugging in.

Check the voltage and the plug on your own model before you buy. The specs can differ.
