Cool!
However – after skimming through the manual – how do I read from a .cpm image
(using simcoupe)?
I opened the Hitchhiker’s Guide to the Galaxy .cpm as floppy 2.
A0>B:
B0>DIR
256 entries of ?????.??? files are shown
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.
B0>A:
A0>fatread b:
That disk doesn’t appear to be fat12/16/32 formatted.
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! ;-)
On another note - how does it play with z88dk – which has a CPM target? (which
I’ve also never
really used since I don’t do C, but it fascinates me and I had some fun getting
it to build).
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.
