 Today I want to tell you about one revision Scorpiona, after 
which will run all the programs switching pages # FD.


  In preparing the material used article:
(C) A. Yermishin, A. Migunov "Rigid decoding port
# 1FFD a PC "Scorpion ZS-256", published in ZXREVIEW # 4-5 1996

  For completion will need two m / K555 (1533) la2
and K555 (1533) ID7 and resistor 10 com.
1.U D53 (ID7) cut from the board H6 and H15 from the body
and H13. New m / ID7 hang above D53, a junction
They each H1, 3, 4, 5, 6, 8.16. H15 and 13 are soldered to the 
cut H15 and 13, D53, respectively. 2.Na H2 new m / ID7 send a 
signal to the H8 la2, la2 hang on the D15 (KP11), soldering H3, 
7, 14 to H3, 8, 16 D15, respectively.

3.Raspayayte wire signals from the computer's motherboard to
La2 and unused items m / s D57, D58 according
this scheme.
4.Na welded together H6 D53 and the new ID7 through resistor 10 
kOhm submit +5 V. 

  That's the whole refinement. Now you can listen to digitized 
melody, using programs such as STS, MIRACLE 128, SIMPSONS 128, 
INSULT, etc.
