Hi,

I added another Disk ][ from my //e and it works fine - so the new
arrived Disk ][ seems to be defected. I will try cleaning and head
recalibration.

I have some photos and related questions:

The Set - is the display stand an original by Apple or third party?

Wich keys do I need to press to do a soft reset (Disk booting again) ?

http://myoldmac.net/picts_static/Apple/Apple%5D%5BEuroplus-ROMs.gif

A bunch of ROMs installed - looks like a second hand shop...
Is this normal ?

Two ROMs have a "MICROSOFT" copyright (1977) - are this the BASIC
ROMs?
Strange to find Microsoft in my Apple...

There is a strange switch on the keyboard analog board -
you can switch between "RESET" and CNTR (Control)?
Does anyone knows for what this switch is for?

Thank you for any help - the Apple comes back to life!
