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

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.
