MAX: The article is based on help for the program
me TASM4`512K (there is such a joke). For
reliability of liability information
I don’t carry it, because check this gadget
there is no possibility due to the complete rejection
presence of Profi.  The original mentions
newspaper ESNO`3, where you can clarify the
data on revision. In the future we plan
I promise to continue making links to sources,
so that in case of errors in the texts you can
get to the bottom of the truth.  The following is text from
help.                                    
                                          
...Now a few words about memory expansion.
Until yesterday I had a computer
Profi, and yesterday there was a certain hybrid called
vaniyaPentagon/Profi v3.2 512k. This is the service
was due to the existence of such a spin-
that modification of the Profi computer, which
makes it port compatible with
Pentagon`512.Now becoming available
four modes of computer operation:               
-PROFI 512                                
-PENTAGON 512                             
-SPECCY 128                               
-PENTAGON 512 + PROFI port 57341 (or
 PROFI 128)                               
    Refinement requires only 2 chalk-
