Can anybody please help me with this problem:
My 90 years old mother-in-law has almost no reading or hearing
capabilities anymore and spends all of her days quarreling. The only
thing she is still interested in is music.
What I need for her is a walkman with no more than one very big red (
alarm - like) button to switch it on and off, absolutely nothing more.
I have good hope that I can teach her in less than 3 days ( if I do my
utmost best ) to press the one and only button to get music on her
earphone. I cannot find a CDRom or cassette recorder with auto-reverse
that satisfies this specification.
So I decided to build one, using CDRom ( Hitachi IDE ) in a box with
a 5V adapter and also a 12V adapter since PC power unit is far to
heavy. ( Question: are there any special specifications on stability
and tolerance on Voltage ? ). What I cannot find is how to make it
spin, using the 40 pin connector at the back. No computershop could
help me ( " we know how to install a CDRom in PC box, that's all" ).
I do have IBM 0662 specification with configuration of ATA connector
40 pin but it does not mention the word 'spinning'. Could it be the
RESET pin #1 ( left in toprow ), but that must be grounded. (
"Hardware reset to the drive; an active low signal" ). If so, what
second pin to use and on what Voltage?
