Ahem... yes - just before reading this I opened the hh.cpm image as disk 1
in SimCoupe by accident and it worked...  Cheers.

Cool!

That's because drive B: is actually the left floppy - or "floppy 1" in
SimCoupé!  So you're trying to DIR a standard SAM format disk - in fact
probably the Pro-DOS boot disk.  The 256 ????????.??? DIR entries is
standard response to an "unknown" format - as far as CP/M goes.

Because it's not!  It's most likely a SAM format disk!  ;-)
  
The drive layout on a SAM with two floppy drives as seen by a freshly booted
Pro-DOS v2.0 is:
  
Drive A - Internal RAM drive
Drive B - Left-hand floppy drive on a real SAM (floppy 1 in SimCoupé) Drive
C - Right-hand floppy drive on a real SAM (floppy 2 in SimCoupé)
  
So to run HHGTTG if you loaded the .CPM image to "floppy 2" in SimCoupé
means you should have moved to drive C: and not drive B:  Of course you
could also use the SWAP command to switch the drives around if you so wish.
So Drive C: could be Drive A: or any other drive on your system.
  
Note to everyone reading this:  The manual tells you all of this...  So it's
well worth reading at least once!  ;-)

I'm not a 'C' programmer either, so have never heard of or played with
z88dk.  However, if its target builds are generic CP/M 2.2 then I see no
reason why the builds wouldn't work.  I might have a look later and see.  I
think I could just about manage a "Hello World" program in 'C'!
  
Cheers,
Chris.
