Atari 520st PS

[hobbyhands]

Hey folks,

 

I finally purchase a 520st, but is has not power supply. I'm not even sure if the computer works. I plan to cobble a psu with atx power supply.  But I don't know what type of din connector it uses. I know it is a 7 pin, but not sure what size?

 

Any links, more info would be much appreciated. Thanks

Should you want to buy one.

I have no idea what size that connector is.

Thanks. Just purchased. One.

I bought two of Short STs recently. I bought them only because they were really inexpensive.  I am currently upgrading them with TOS 1.04 and 4 MB of memory.  One had a broken top case, but I found a New Old Stock (NOS) case to replace it with.

Do you have a floppy drive for yours?  It can take a minute or two to boot instead of seconds without one, but it will eventually boot.
