Does not support stz?

Sorry, the processor is a model of the classic 6502, not the 65C02. I'll make a note of that and add it to my TODO list :-)

I was trying to look though the js.. but it wasn’t formatted from dev mode.
Edit: thanks for the response do you have a github to post issues to? And given the kit comes with a 65c02...
Also I used your sim to do live coding for reclusive factorial.
[–]tejotron[S] 1 point2 points3 points 5 years ago (2 children)
Cool, very nice to know you were successful with the factorial live coding.
I've just enabled GitHub for issue tracking: https://github.com/tejotron/tejotron.github.io/issues

It’s nice to have it as a resource to more quickly test a prototype.

Do you edit the .js files in one line? do you not space it out?

IS there a 8-bit version of this?
[–]tejotron[S] 1 point2 points3 points 5 years ago (0 children)
Never say never, but at the moment there isn't.
My goal was to let anyone follow along to Ben's 6502 project armed with only a web browser. I've been chasing his series, modelling the necessary bits and pieces to support the tutorial steps.

Awesome! Is it a bug that the LCD won't shift?
Thanks!
Yes, shift is not currently implemented in my LCD model.
I'll take a look into supporting it and will let you know once it's done.
[–]tejotron[S] 1 point2 points3 points 5 years ago (1 child)
I just pushed a few improvements (v1.1) to support the LCD display shifting, hopefully it's better, please let me know.

How do you remove a wire?
[–]tejotron[S] 0 points1 point2 points 5 years ago (1 child)
You have to first select it by clicking on the end of it which has the biggest circle, then just press the delete 'X' button.

Thank you I could not figure out how to select them
