Enclosed is the new layout to be added to the logic tests.
Logic test done with the modified DM74LS54N (National Semiconductor) connection to the programmer (connection drawing attached).

WARNING!
The 7454 and 74LS54 integrated circuits differ internally.

To check the logic vector for testing the 7454 integrated circuit, the test was performed on a real CEMI chip from Poland.
