1) Find image online
2) Use HxC software to convert it to .SCP format
3) Use SCP to write image to disk

The problem lies between #2 and #3. The HxC software does not properly convert the image, i.e. Byte $04 the Mfg/Disk_type is set to $14 when it should be $41. Byte 05, the #Revs is set to $03 when it should be $01. If this is set to anything other than $01 the SCP software ignores Byte $08, Bit 1 which tells the SCP software to use index mode. 

The SCP software also does not know what to do with a 40 track, single sided image and tries to write it as a 20 track, double sided image. You can use HxC to add a Side 1, fix the bytes explained above with a hex editor and the SCP software seems to be happy and write correctly but the disk does not work.

To work around this, I took the original image, converted it to an HFE format which will work on a Gotek. I was able to boot the TRS-80 Model 4P from the Gotek and then copy the image running on the Gotek to the floppy disk. Reconnecting the floppy drive as D0 I could boot from the floppy disk. I then imaged the disk with the SCP and wrote this image back to the floppy disk and was able to boot the machine.

The files I have created during this saga are:
TRDOS80.IMD - Original single sided image from web. For 5.25" DD media.
TRDOS80_IMD.hfe - Original image -> HFE w/HxC. Works on Gotek.
TRDOS80_IMD.scp - Original image -> SCP w/HxC. Writes as 20 track DS instead of 40 track SS.
TRDOS80_IMD_2S.scp - Original image -> SCP w/HxC, added side 1. Seems to write OK, does not work.
TRDOS80_IMD_wSCP.scp - Disk make w/Gotek imaged with SCP. Works when written back to disk.

First I use the HxC Floppy Emulator software in Windows 10 to convert from DMK or DSK format to SCP format.
 
Then I use the SCP software/hardware to write the physical floppy diskette.
 
As I said, this works fine for most MFM-encoded formats (Kaypro, TRS-80, Color Computer, TI-99/4A. etc.) but after going through the entire writing process with no error messages, the SCP-created CP/M Plus diskettes are not bootable on a TRS-80 Model 4.
 
Finally I tried using HxC to create an IMD image which ImageDisk was able to use to create bootable floppies from DOS.
 
According to ImageDisk, Tandy CP/M Plus uses a dual-format. Track 0 is 18 sectors of 256 bytes but the other 39 tracks are 8 sectors of 512 bytes. I believe SCP software could be modified to write these disks successfully. If you’re interested in tackling the job, I can provide either DSK or DMK images of the Tandy software.
 
Let me know if you’d like copies of the diskette images.

I got my SuperCard this week, and I have been playing with it a bit tonight.  Thanks for the quick shipping!  It works great for making backups of my working disks, and using them in an emulator, but I also need to go the other way.  Thing is, I purchased a couple of KayPro systems, CBM 8032 systems, and (TRS-80 Model 1 and 3), and they all came with system disks, but....These systems were LITERALLY barn finds.  They had been sitting out in unheated sheds in rural Alberta, where temperatures in the winter get to -40C on occasion.  The disks also are very dirty, and warped. So I have systems, that I think will work (I have cleaned them up and tested as best I can with no disks), and original disks, that do no have a chance of working.  I would like to make new disks form images that I can download, but I can't seem to get that to work.  When I use HxC software to convert the files to SCP files, and load them, it always defaults to Atari ST disks.  These systems use DD disks, not HD disks, so I think I need to use the C64 setting to get double step to work.  Not sure where to go from here??  Is there any way for me to do what I seek?

Thanks for a great product, I am looking forward to learning more about what I can do with it!]]>

So looking foreword to when it will read and copy them.

Thank you for Super Card Pro.
