View Full Version : Vic 20 Power Supply

October 4th, 2006, 02:21 AM
I have a phase 2 power supply and a phase 1 Vic 20, would it be possible to convert the power supply using a 7 pin female connector and a two pin male connector connected to the correct two pins?

I have been unable to find a power supply for a phase 1 VIC 20

The topic has been discussed on the VIC-20 specific forum Denial (http://sleepingelephant.com/v-web/bulletin/bb/index.php) from and to. The two-prong PSU delivers 9V AC, up to 3A according to the power supply. The 7-pin DIN PSU delivers both 9V AC 1A and 5V DC 1.5-1.7A depending on exactly which brick you have. The question is how much power the VIC-20 really requires. It has been carefully measured how many watt it uses in various situations: using tape recorder, using disk drive (which however has its own power source), playing sound and so on. From what I remember, most functions would function using a modified PSU, but perhaps you have access to another transformer that outputs 9V AC only at a higher effect and could modify that. The userport also relays the 9V AC line. Otherwise you are supposed to be able to feed it a 7.5 - 9V DC voltage only.

Sorry for not being able to give you a more definite answer.
