hi
thx for the reply
i have commodore 64 from the US and here it is 220 volts
and the pins for the electric socket are different
so i need a converter but in order to buy one i need the 'Whats'
from the original power supply in order to buy the right converter.
the drawing doesn't show the 'Whats'
so i need the specific specs of the power supply
i am sure it is written on the back of the original power supply
what i have is not the original (and even looks home made or something) and it shows nothing

It's power and it's 'watts'.

It should be stated on the power supply but if it's not you can use the current (that should be on there somehere) to work it out.

Power (in Watts) = Voltage (in Volts) x Current (in Amps)

So a uk device with a 3A rating will need:-

240V x 3A = 720 Watts

Here is what is molded into the plastic of my power supply...

Input: 117V AC 60Hz 40W
Output: 5V DC 8.5W PIN 5 and 9V AC 9VA PIN 6/7

Does that help? I'd be glad to send you a power supply (I have spares) although postage to Israel might be a wee bit expensive.

The info you where after is there -
40W = 40 Watts



However, whether a converter will work is another matter though. Most will just convert 220-240V to 110-120V but it will not change 50Hz to 60Hz. That might not be important on the C64 ( unless the 9VAC is used for clock generation?). The fact the USA C64 will output an NTSC signal rather that a PAL one will be an issue though

thx

hi
all thx all for your help
i have a 40W converter from our power 220 to the usa 110
and it should work but some how my commodore shows scrambled screen on start up and nothing that i do on the keyboard gives any reaction.
i don't know if its the commodore who is not good or the power supply or the converter.
thx anyway
