This is really great!  Thanks for putting this out!

The only problem is I'm already working on 2 other projects!!

I looked over your code, and it looks as though you've implemented nearly a full
IDE interface there.  This is going to be a good starting point for a lot of
other projects.  I can't see anything right off the bat which I would change,
but when I build one I'll probably come up with a few things...

I was wondering, though, the beginning hook-up listing shows:
;       PORTC
;       0       3       D0
;       1       5       D1
;       2       7       D2
;       3       9       D4
;       4       11      D5
;       5       13      D6
;       6       15      D7

This doesn't seem to match.  D3 is not included on the right, but looking at an
IDE pinout
www.sonic.net/~alanwall/hwb/co_IdeInternal.html
it looks like you've almost got the listing backwards...  Is it supposed to be:
;       PORTC
;       0       17      D0
;       1       15      D1
;       2       13      D2
;       3       11      D3
;       4       9       D4
;       5       7       D5
;       6       5       D6
;       7       3       D7

?

Everything else appears to check out...  I would like to build one just for the
fun of it, alas, time is in short supply lately.  It would be nice to have an
LCD hanging off it, which is what I would be aiming for.

Thanks again!

Thank you for pointing this out assume the following portc is the lower byte
port
and portd is the upper port ie portc,0 = d0 of the ide connector

so, it looks like you have to specify where you want it to start and stop
playing?
The next step is to read the TOC create some type of list from that on th
PIC

looks like it is a matter of sending  8c 0 e 0 0 0 0    , and getting 9
bytes back.

anyone who is interested I have a couple of links that may be of some use

www.geocities.com/SiliconValley/Hardware/2342/mp3player.html
this is a 68HC11 based MP3 player with an IDE CD-ROM, I suspect this will
have mush pertinate info.
www-stu.cai.cam.ac.uk/~atm26/electronics/panasoniccd.html
list of error codes


ehh I gota run ...ill post the rest latter ,
sorry
Ryan
