Hello!
I spent the last few weeks just tinkering around and having fun, and I ended up making a (somewhat) working Apple I emulator!
Even if it's a little rough around the edges (I don't think BCD works that well, it's not cycle accurate, and no cassette loading), I'm quite proud of it.

It runs in the terminal using a minimal TUI.
Here's a few screenshots:
I probably won't be maintaining this, I'm pretty busy most of the time :P
