Is it possible to implement the MGT disk format into this so it can be used with aPlusD and a sam Coupe?

Maybe, did you have some files somewhere and/or a file description ?

[caver99]

I can get some mgt and sam disk images for you.

SAm Coupe disk format is 80 track 10 sectors with 512 bytes per sector - http://en.wikipedia.org/wiki/SAM_Coup%C3%A9#Disk_drives

And the MGT file format is a raw file format ?

This is a section taked from the tecnical manual for the plus d

"6. DISK LAYOUT
==============

The disk has 80 tracks of 10 sectors (512 bytes double density, 256 bytes low
density) each, for a total capacity of 800KB (DS/DD).
The first four tracks of the disk (tracks 0-3 side 0) are reserved for the
system and contain the disk directory, leaving 780KB available for user data.
The directory consists of 80 consecutive file descriptors, each one taking
256 bytes; thus, the descriptor of file #48 resides in the first 256 bytes
of sector 4 track 2.
The directory has a fixed dimension and can only contain up to 80 files.
UNIDOS overcomes this limitation introducing subdirectories and allowing to
specify the maximum number of file entries for each directory.

Disks formatted with DISCiPLE or +D can be read and written by common PC
disk drives and viceversa"


Hope this helps

ok sad and mgt are pure file format.
So to load them you can use the "Load Raw Image" button, and set "Sector per track" to 10 and "GAP3 lenght" to 34.
After this click on "Load Raw file" and choose your sad/mgt file image.

I will released a new version of the tool to make these steps easier.

[caver99]

Thanks for that.
I have had a go but comes up saying disk missing, dont surpose you have have any idea what setting i would use for j3?

[caver99]

Its ok found manual and set it to a: works a treat many thanks.

Would this be possible to have in the software so we can just load them in.

Just a thout love thsi so far.
