Enclosed is the new layout to be added to the logic tests.
The test was performed on the M74LS91P (shift register 8-bit) chip from Mitsubishi.

I am giving the correct version of the tests for the 7491 chip. The previous version is wrong.

An interesting fact is that this IC cannot be recognized automatically (Auto Find), possibly because the first few lines of the logic vector do not validate any logical values.
