CoCoSDC documentation?

Is there documentation for CoCoSDC beyond the http://cocosdc.blogspot.com website?

I am wanting to know more about the Enhanced FAT support mentioned in the MCU FIRMWARE 115 changes document:

"Additional FAT file manager operations are now provided in the firmware. These include the ability to
delete and rename files and directories, to create new directories and to query the size of the file.
Currently these features can be utilized only through low-level calls to the DSKCON routine in SDC-DOS or
by communicating directly with the CoCo SDC hardware."

This is most excellent (assuming earlier versions had the basic directory reading commands).

PEEK for detecting CoCo arrow keys, etc.?

Does anyone remember the PEEK locations for detecting arrow keys (preferably one that works from 1980 CoCo
1 to CoCo 3)?

CoCoSDC: Using RS-DOS for new .DSK image file size?

Darren,

I am writing a series of CoCoSDC articles on my www.subethasoftware.com site, and as I work through things,
I come up with more questions.

In my RS-DOS days, we had patch programs we would run that would set Disk BASIC to 40 tracks, and set the
hardware to use 6ms step rate for faster and quieter disk access. Once this patch was ran, all commands
worked with 40-tracks:

DSKINI - format all 40 tracks
BACKUP - backup all 40 tracks

Does CoCoSDC DOS take in to consideration this max track value when creating the new .DSK file? I believe
creating a pre-formatted DSK image file is merely a convenience to the user so we don't have to format each
one we make:

DRIVE 1,"NEWDISK.DSK"
DSKINI 1

Nice. But if CoCoSDC DOS used that value in the ROM for the size of the .DSK file, it could automatically
create a 40-track (or 42-track) disk image for the user, too, the same  was DSKNI does.

I expect if I have the patch ran, and my system is set for 40-tracks, when I do this:

DRIVE 1,"40TRACK.DSK"
DSKINI 1

...the DSKNI process will format to 35 tracks, then continue going and the .DSK image will be expanded.

Ultimately, I need to go through all my old disks and reorganize them back down to standard 35-track disk

clever idea didn't work

VGA monitor on my coco3 is great, thanks to Roy Justus converter, but no 
artifact colors on old games.  TV on my coco3 great, I get colors, but 
can't do 80 columns.  Epiphany:  I found an LCD TV sitting here, it has 
composite in, and VGA in.  So I hooked both up to my coco at the same 
time, now I can just hit the "input" button on remote control to switch 
between VGA and composite signals at will.  Perfect, except:  The TV 
will not display the VGA signal, says "mismatch resolution."  But the 
manual for TV says it supports 640x480, 60hz.  I plugged converter into 
a normal vga monitor, worked perfectly, brought up the menu and it says 
640x480 60hz. So.  Maybe TV doesn't support that res, and manual is 
wrong.  Or... could there be some other reason the converter output 
would not be recognized universally?

Re: The CoCo Lounge


Happy Holidays everyone.
Just a small heads up that in January I will be listing everything I have for sale at the lounge on ebay to blow
out the old stock and make room for new stock. Of course prices will be adjusted for ebay and shipping will
not be included in the ebay prices. Now is your best and last chance to pick up something from the store.
http://amigalounge.com    (main site)
http://thecocolounge.com    (just the Tandy stuff)
I can not guarantee shipping in time for Christmas, but I will be shipping all the days the post office is open.
-Thanks
-Glen

P.S. Remember the BEST way to get a hold of me is through Email at the site or the hotmail address, as I don't
read the list here but once a week or so.

CoCoSDC question: default .DSK size?

Since I cannot wait until I get home to try it out (I received my CoCoSDC from Ed, and enclosure from Tim), I
wanted to ask what the default disk image size is if I make one like:

DRIVE 1,"NEWDISK.DSK",NEW

On many of my disks, I had a small loader program I would run which patched DISK BASIC for 6ms step rate and 42
tracks to get a bit of extra room. How can I back those up? I expect it would work if I used SDF format:

DRIVE 1,"42TRACKS",NEW+
DSKINI 1

...which would send format commands out to 42 tracks, and then it should work, yes?

Does "NEW" create a 35 track image by default, or worst-case 80 track (wasting space)? Or does it have
nothing in it until something is written and it expands to that size?

Thanks...
