I just picked-up a Macintosh Color Classic with an Apple IIe card. I've never used one of these before but was able to get it to enter into Apple IIe mode. However, I cannot seem to figure out how to get out of this mode. I tried exit and common keyboard shortcuts, but wasn't able to do it.

However, one shortcut (I believe it was Command-Power) resulted in a popup window on top of the Apple IIe screen like so:

enter image description here

Sorry for the image distortion; appears to be a screen refresh issue. It appears this is some kind of command prompt, but everything I try (exit, quit, q, etc.) doesn't do anything.

Does anyone know how I can exit this popup screen as well as exit the Apple IIe mode? I don't want to pull the plug, but not sure what else I can do.

Thank you.

  • I think either "q" or "x" or "quit" or "exit" to get out of the Mac Debug monitor window. Then, there's a hotkey to toggle you from the Apple //e mode back to the configuration menu for it - I think it is Cmd+Esc, maybe?

  • Thanks @BrianH. However, I tried those keys and they do not work to exit the debug window (is that what this is?). I type those, press enter, then it just deletes the line and does nothing else. May 29, 2020 at 17:24

    Ah, It's "G", then Return, to exit the debug window. en.wikipedia.org/wiki/MacsBug

According to the Apple IIe Card Owner's Guide, Command-Control-Escape will open the Option Panel, which includes buttons to "Quit IIe" and "Restart IIe", among other things.


The window shown on the screen shot is not MacsBug, but some badly documented, most likely ROM resident debugging facility popping up when MacsBug is not installed. @BrianH mentions correctly to get out of that window with G and Return, though.

  • Poorly documented, eh? Check out Technical Note 1136 which describes all the commands. For example mirrored at fenestrated.net/mirrors/Apple%20Technotes%20(As%20of%202002)/tn/… May 31, 2020 at 3:00

  • Back in the 1990's, there were mainly Manuals and Books. Every program you bought had a manual. Books (like Inside Macintosh) sometimes served the purpose of a manual. I don't know about Technotes being available without requiring some sort of online access. So, I conclude, compared to yesterdays standards, it's poorly documented.

  • Addition: According to the TN, MicroBug is mentioned in the MacsBug Manual. I can't recall this, even if I've read it some time ago.
