 Hello everyone. When connecting Temuhoro, you can
Dema to my PROFI`ku I encountered one
another unpleasant feature of this computer.
The fact is that it has 5 bit #FE port in
you won’t find it anywhere in the board, but
there is an unused m/s trigger element
TM2 (U29),on which we will do this
signal.  The first half is used for
generating a signal for recording on magnetic
phone (it will go to IN_MODEM), and the second
will be slightly hung with jumpers. Here

 Вот, собственно, и вся доработка. Только 
хочу  сказать,  что не плохо бы поставить 
еще  и  буфер на выходы (например на АПб, 
ИР22,  ИР23).  А  то может случиться, что 
ТМ-ка сгорит, вплоть до короткого замыка- 
ния (я поменял их штуки 3 уже). * * *                   
                                          
 Yes, it’s a contagious thing to hang up all sorts of things. 
Weiss on your poor computer.  Here at 
connecting COVOXa encountered a problem 
incompatibility of this device and the printer 
ra.  The latter refused to print normally 
thief. This glitch was fixed by installing 
ki buffer m/s between COVOXomand the bus 
(it turned out to be a nice bug :) ).            
   A few words about INTe. My research 
studies have shown that INT (as well as producing 
computer activity) depends on such mukpoc- 
xemku, like the firmware RF2.I have 3 of them -

ki, and everyone shows different INT. One 
Pentagon, the second is just below the corporate name 
no, but the third one is a hell of a thing 
coy.  Naturally he left the Pentagon. 
Its length still had to be adjusted 
RC circuit,and this whole thing was tested in
