 HI!!! Well, some are probably already shouting “hurrah, we’ll play
games on CD!!!", so, those who shout like that can shut their mouths
and read what I write.                                       
 I connected the CD only at the music level, i.e. programs from it
It’s impossible to read and it looks like it’s not possible at all on SPECCY. Ho-
if I recognize the IDE interface pinout, then who knows... CD
connected with two bits via the BBSS I/O port.  From CD
you need to bring out 2 wires from the EJECT and PLAY buttons. I bought a used one
new CD-ROM (two speeds) for 200 thousand rubles.  The manufacturing company
tel - AZTECH. The CD has the two aforementioned buttons.              
 Buttons are considered pressed when a local signal is applied to one of the contacts.
gical ZERO. If the button is not pressed, then its contact is at 1. It is necessary
solder two wires to these same contacts, and their other ends
hook to the last two bits of port 31 (#1F), they cannot be used with a joystick

PROFI I write the number 128 to port 127. All bits of port 31 are set
new to 0. Now you need to set its last two bits to 1,
otherwise the CD will not respond to button presses. INSTALLATION NEEDS
but do it programmatically, and CD won’t even have time to understand that the buttons are on
momentwent to 0.                                   
 If BBSS is not installed and the CD is connected, then it works like
usually. It's just that the BBSS pins are in the Z state.             
 Why is all this needed: In general, with the help of a computer you can implement
start listening to a given track, VIEW M0DE (quick overview of
disk) and the mode of listening to the selected order of Mouzons, also
CD database is possible.                              
                                                                
 Now about the CD.                                                   
                                                                
 If you want to use CD PLAYER, you will need CD R0M  
must have at least two buttons, it is advisable to take      
the same as mine. Here's what it looks like:

 Если вы собираетесь слушать на CD только музыку, то можете спо-
койно брать односкоростной CD, так как все эти сверхскорости ис-
пользуются только при чтении программ, музыка же  прослушивается
на 1 скорости.                                                  
 Ну вот в принЦипе и все...                                     
                                                                
 Кстати, может у кого есть документаЦия на распайку IDE и сигна-
лы CD R0Ma, то не сочтите за труд, передайте SH0R KANy,  который
