1030 & 212 Power Supplies

[gilsaluki]

Question: Can a power supply from the SX212 power the 1030 modem safely? I don't have a PS for the 1030. Sources say the 1030 had its own unique 9VAC/600mA PS. The SX212 is rated at 9VAC/500mA, also can be used with the 2600. The plug is the same. Will I do harm to the 1030 using the SX's PS?

 

Also is there any Dial-up BBSs left to call?

Don't use a 9VAC PS with a 2600. The VCS needs 9VDC.

 

Don't know about the modems but before you try make sure both are AC (or both are DC).

I'm pretty sure the SX-212 is 9VDC, and is the same as the XEP-80 and 2600 adaptors.

From the F.A.Q:

9 V DC  500 mA  (4.5 W)  Atari#CO16353/CA014034/CO10472/CX261    XEP80,SX212,2600 (center positive)

9 V AC  5.4 VA  (600 mA)  Atari#CO62195/CO17539    1030

So, no, definitely not interchangeable

Thanks for the info.

To make the story complete, in this 9 VDC case:

• 500 mA = 4.5 W = 4.5 VA
• 600 mA = 5.4 W = 5.4 VA

This is the max. a PS can deliver, so, using a 600 mA PS with a 500 mA device is o.k. The remaining 100 mA is just not used.

 

With a 500 mA PS and a 600 mA device you're 100 mA short. This just works in most cases but isn't recommended for extended use because a PS is a pretty stupid thing and tries to deliver the extra 100 mA anyways with the result that it's getting hotter and the risk it'll just break.

Thanks. I have 1030 with no PS. I also cannot find any dial up BBSs, so I guess the point is mute.

moot

moot, yeah...that word.
