Iron - The scheme for a music processor (continued).

                 IRON

 (C) Dimon



     Today's article will be wholly and
devoted entirely to some changes in how
and additions to the article in last issue.
Unfortunately, in the last issue, in the first
scheme was made
annoying opechatka.Tam
element has been implemented and, as we need
ILI.Tak element here,
illustrated Nye scheme does just that delaet.Diody tezhe-CD 522 
(1), but the resistor rated at 750 OM.Kak see scheme 
characterized by the polarity of connection of diodes, as well 
as the denomination and the way to connect a resistor. If you 
are on board is free or

elements, or you can more easily soldered chip than the diodes, 
then Using this scheme

can realize the function performed
previous shemoy.Mikroshemu better to take
1533 (555) serii.I not forget to bring
at 7 and 14 foot power bus.
Scheme, which should start signal M1
Can be realized with
by diodov.Diody
Series KD 522 (1), resistor 5.1 Com.
Also, if you have the scheme wound AY-shki
BEEPER, I advise him to tear off from there, and
apply to the dynamics of otdelno.Eto desirable to do so as 
BEEPER adds noise in the stereo channels AY-shki.

Well, like with AY-shkoy really
vse.Vse circuits tested, so you can
easy to take up the soldering iron.
