Need help with Atari 1050 disk system - test-drb@ccmp.vtda.org

18 Apr 2004

Hi Adrian,

...
   #1) Can anyone
tell me the power requirements of this drive? 
If you go to www.classiccmp.org or
google and search the archives you'll
find a thread or 2 on power supplies for the Atari 400/800 - these are the
same ones that run the 1050 floppy. The one I have here that recently
powered my Atari 400 and 1200XL is marked as 9.5V 1.5A but it's acting up so
my DMM won't tell me whether it's centre positive or not. 
Thanks for the info - I did a bit of looking and found several references once
I mentioned "Atari 400" - turns out the supplies are AC, which probably
explains
why your DMM is having trouble determining the polarity.

...
   need some
sort
     of boot disk... Anyone out there with one that can make a 
 copy or send an
     image (Can Atari images be read/written on a PC's drive?) 
I don't think so, you might need an SIO2PC cable to do that. Hopefully Curt
will be along with more info shortly, as long as he's been allowed back in
after his out-of-office faux pas the other week :) 
Ok. I'll do some more looking around as well. Do you know if there are any disk
I/O functions build into the ROMs of the computer and/or drive (like the C64),
or do I absolutely need a boot disk in order to make the drive do anything (so
I can figure out if it works or not)?
