 Hi all Speccy World!           
                                          
    When connecting Temin's modem, the moisture
dealers of some computers, for example
PENTAGONA 2+,  may break a little.
Because the circuits of these computers do not use
uses  the 5th bit of the #FE port. Below
here is a circuit that will save your PENTAGON
from this minor inconvenience.              
  There is no need to cut paths.  Will need
only one small item and a few centimeters
wire ditch.                              
                                          
       Actually the improvement scheme.

   The easiest way to do this modification is this: 
                                          
   1. MikrukhaDDx place on top ofDD10
(TM2);                                    
 2. Solder 1,3,4,7,14 legs DDx corresponding
respectively to the same legs yDD10,and mainly
bend the steel ones to the sides, first
ykopotub them;                              
   3. Required forVICOMMasignal bit 5#FE
