[Coco] 2 x 3.5 Drives on CoCo

[Andrew]

Jason,

If you're willing to spend a little money, I am sure you can find a 
suitable power supply at All Electronics or some other online surplus 
electronics retailer; something like this:

I know I purchased one from All Electronics several years back for an 
AMD586-based motherboard MP3 player project; it ran the hard drive, the 
motherboard, and peripheral cards (ethernet and sound) - on occasion, as 
I was developing hardware interfaces and such (keypad + LCD hanging off 
the parallel port), I needed to use a cd-rom drive and floppy, and it 
powered those fine as well.

If that doesn't work, then if you can find an old TIVO, they have some 
excellent power supplies in them that are fairly small, and easily removed.

Another possibility (though more expensive) is a Pico-PSU - they run off 
a (hefty) 12 VDC PSU, and are meant for Car PC and other embedded apps; 
they don't look like much (they are really small), but they should be 
powerful enough for running a couple of floppy drives. I have one in a 
robotics project that powers a Micro-ATX ATOM motherboard, two 2.5 250gb 
drives, a RAID card, and a wireless router:

Hope this helps!
