irline3: 996, // internal signal: PLA input - ir0 AND ir1


But analysing the circuit I see that irline3 is actually ir0 OR ir1:

Edit: to clarify, the bug is just in the comment not in the code.

Quite so: 1133 is the output of a NOR and it's followed by an inverter.

You can watch the signals like this:

I've sent a pull request to Barry: anyone could do the same, by using the 'Edit' button on github - you need to be logged in, but accounts are free.

Cheers

Good, didn't know that I could edit the source.

Note that Barry won't necessarily act immediately to pull requests! And it's another step to publish. So please bear in mind this is a volunteer website. For many experimental purposes, running your own fork in a 'gh-pages' branch is a good way to proceed.

OK, that fix is deployed now. You may need to force a refresh.
