[Coco] tandy 1000 ex/hx external drive

[Bill Pierce]

I have one of those "EX/HX" drives that a friend gave me years ago. He had converted it to the Coco already when I got it. It's the one RS sold that was a small white case with no PS, just a drive in the case.
His method was to use a "standard" Coco drive cable and PS cable extender.
My drive has a mounting plate in it (5.25 to 3.5) with a 5.25 drive cable end to 3.5 end and the same is done for the PS. This plate can be removed and mounted in a standard Coco double drive case as well (where mine resides now). I have no clue where he got the mounting plate or if it was in the drive already.
I have come to cherrish that mounting plate as it allows me to use any 720k 3.5 drive with my Coco drive system (as long as it has jumpers). I keep the original case just in case I want to re-mount it someday, but for now, I like it in my Coco drive case.
If I get a chance, I'll post some pictures of it.

I have a  tandy 1000 ex/hx  external  disk drive  does anyone know  how
 can power this so I can use it on the coco
---------------------
That drive has power fed to it over the drive cable, IIRC through two of the 
ines normally grounded. What you'll have to do is open the drive case, find the 
ower connector (should be a regular connector with wires jumped over to the 
rive data cable), cut them, then use a wall wart to feed it power. It may be a 
5V only drive. If so a single 5VDC wall wart will work. If it needs +12V you'll 
ave to use a pair of warts -- one with 12VDC also. That is the easiest way to 
ower it. You can use any +5V/+12V power supply. If you check the surplus 
ompanies (http://www.allelectronics.com/, http://www.alltronics.com/) you can 
ind power suitable switching supplies.
