I have made a new repository at GitHub about the 741.
The Readme file says at this moment:

This project tries to give some more details about simulating opamp 741 with SimulIDE. It uses this book:

https://diagramas.diagramasde.com/otros/41%20Projects%20using%20IC%20741%20OP-AMP.pdf

A text file is added with more details about each simulation and will be updated now and then.
The simulations are made with SimulIDE 0.4.15-SR1 and can be downloaded here:
https://www.simulide.com/p/downloads.html
Once downloaded there are more examples about Opamp circuits at
SimulIDE_0.4.15-SR1_Win64\share\simulide\examples\OP_Amp
The Github repository starts at example no. 21 from the book.

***************************************

I hope it will be a nice addition to the Opamp-examples that are already available in SimulIDE and some will overlap.
Pdf examples 16-19 and perhaps more to come are discussed in this Help-topic: https://simulide.forumotion.com/t176-opamp-and-trafo-circuit
Of course not every project will be placed here, that's why I created the Github. There are 20 more to come and I haven't looked ahead what they contain.
These are Simulide examples with the path where to find to them

And this is pdf-example no. 21

The simu-file can be found here:

From the same opamp 741 book, pdf page 27/42, examples 25-28, a monostable and a bistable multivibrator, a trigger pulse generator and a flasher.

Simu-file is here with title 25-28

Examples 29 to 41.
Some I don't get to function, this does not mean it's because of the simulator. There can be several reasons, for instance when I don't know what the input signal should be. More details are in the Help-topic >
https://simulide.forumotion.com/t176-opamp-and-trafo-circuit
Example 40, for some reason the generator has to be started before the 12 Volt button.

In the last opamp example no.41 there is a Programmable Unijunction Transistor (PUT).
This is a very nice webpage with 16 examples of the Put:
https://www.instructables.com/Circuit-Collection-of-the-Programmable-Unijunction/

I have placed these circuits in Simulide 0.4.13-SR5
