Hi Fredric,

I think it's possible you've got 3 bad system disks. Although 8"
floppies are fairly rugged, and seem to survive much longer than
either 3.5" or 5.25", you could damage them in a CMI simply by
switching the machine off or on with media in and the drive closed.
Modern PCs generally don't do that.

So yeah, if you find no willing contacts to do it in Europe, I'm happy
to copy you a system and utility IIx diskettes. Just tell me where to
send.

...unless I've blown all 6 of mine, too

 :-D

The fact that it loads QDOS, etc makes it sound like your base 6809
machine hardware's healthy, however...the master card (the one at the
left) may be bad. That, or a faulty IIx channel card can halt an
otherwise good CMI boot. Also, less probable, as it's tested at
powerup, is a main RAM error.

You should get yourself a pdf of the IIx service manual!

Cheers,

Joe

Hi Joe, thanks for your reply. I sent you an email.
