Using Stamps with SCSI
G'day all,
New guy here from Wellington, New Zealand.
Been playing with the Stamps since Xmas 2001. Dreamed up a few ideas
already, and implemented some.
What I'm looking at, is turning an old SCSI CD Drive in to a stand alone CD
Audio Player.
Has anyone toyed with this sort of idea before? I have the SCSI command set
for CD Drives (from the T10 site), but one guy reckons the Stamp may not be
able to respond fast enough, and perhaps I'd need a SCSI controller chip in
the circuit as well.
Any ideas?
Visit my website below, and click on Electronics, then follow the links to
see what I've experimented with so far.
Cheers,
Ben.

Robert, I suggest that you review your processor requirements for your
project before you elect a Stamp or any other micro controller solution. The
Parallax Stamp is a fine product. Your question of how much and when should
follow the understanding of your requirements and not lead your selection
based on price or whiz bang.
Steve.

creative labs (Nomad player) did such a good job with their system for
$250, I figured I could not touch it for the price. Nice Idea!!

I am also from Wellington! Neat to see there is another Stamp/electronics
geek in the area ;-)
If you want to have a yarn flick me an e-mail at jamesfit@p...
Might be useful to have a local guy to coloborate with sometimes ?
Cheers,
James Fitzsimons
P.S sorry to the rest of the list for the noise. Couldn't find Ben's
personal e-mail to take it off list.
