About: Hardware Question(s)...
Was looking at the RockBox schematics and the specifications for a chip
inside (ISD 200 ATA-USB-Processor Bridge) and wondered how could the
RockBox be mixing 3 and 5 volt parts?
Please correct me if I am wrong, but the ISD 200 is a 3 volt part and
there are pages (specifically the pages at funmp3players.com) that talk
about adding a standard 5 volt hard disk drive... What's up with that?
Just looked up the hard drive Richard (on this page:
http://www2.funmp3players.com/reviews/modify/) claimed came in his
Jukebox 6000 and it's a 5 volt part as well.
Hum, lots of questions, I know. But, could someone tell me about the
schematics on the http://rockbox.haxx.se/schematics page? Is the
"Junkebox 6000" schematic the 3rd revision of the Jukebox Recorder? And
the link to the schematic below called "Jukebox Recorder" the 2nd
revision? I ask because in what I think is the 2nd revision the ISD 1.8
core and 3.3 edge voltage pins are all connected to Vcc. But in what I
think is the 3rd revision, none of the pins are connected. Interesting...
...thanks for reading my questions / ramblings,
