Re: Apple //e diagnostic ROM card information

It appears to be used for advanced Diagnostics for the Apple ][e. Not a lot of Application Information.

Some Info at The Apple II Documentation Project .

Some more info at ProgramD.com.

Re: Apple //e diagnostic ROM card information

Hello and welcome knight61,

I own a card like that.
It contains a program that can test hardware (CPU / RAM / ROM), lores & hires display.
Just insert the card in any slot and if the red swith is in correct position, it will take over the machine at boot time.
In the other position, the Apple //e will boot as usual.

ROMs have been translated into several languages. I have the German, French and English versions so far.
I've made a couple of pictures but I don't have them with me right now.
I can upload them if you're interested.

[edit] Here are the pictures.
