@org, okay, thanks!

Thanks. I and my students will look into it.
Which version of the circuit is the most recent one, the one currently at GitHub (shown below left) or the one described in the documentation (Breaking NES Book 6502 Core Rev. B4) (shown below right)?

If I'm not mistaken, the file named 6502.circ currently at https://github.com/emu-russia/breaks/tr ... 02_logisim, when opened in Logisim, looks like below.

@org, my students downloaded the Logisim circuit currently available at github, and they're getting errors when they run the Logisim circuit. The 6502 circuit has wires that are "red" and in error (SB OUT, DB OUT, etc.). Has this been fixed?

@davidmjc, thanks for your reply. For this semester, I'm asking my students to implement a 6502 by converting the Logisim design (discussed in http://forum.6502.org/viewtopic.php?f=8&t=6903) to a Digital design. Perhaps next semester I'll ask them to convert your transistor-level design to a Digital ...

To BigEd and org, thanks! So the orange hexagons do not denote anything different about the transistors, just the fact that the nodes associated with the transistors are special. (I didn't think of hovering the cursor over the hexagons.)

@org, thank you very much. I'll show you their work when they're finished (a few months from now).

@org, I am a college teacher at a Philippine university and I would like to assign as an undergraduate student project the task of converting your Logisim design into a Digital design. (The Digital software is the one at https://github.com/hneemann/Digital.) It will be made very clear in the ...

@davidmjc, Hello! I'm trying to use the circuit diagram you made to implement the 6502 using Digital software. (More information about it here: https://retrocomputing.stackexchange.com/q/24083/11421.) What do the transistors with an orange hexagon mean? What's special about them? Are they just ...

Wow. Thanks for this!
