UNKNOWN DSK FORMAT - HELP NEEDED!

Not yet all things done!
There is an array of some 104 discs with a special format; they are 224,016 bytes long.
They contain scores in ASC format, but the directory seems to be partitioned.
I am afraid that most of the songs in the discs are already in our big pack, but if
someone could give us a clue of how to process them, maybe it could be worth
listing the contents and trying to get just the 'new' files.
Any hint on machine, emulator to use, whatever could be of help!

I attach here a zip with three of these discs

Thanks beforehand

Unfortunately the keyboard is the CoCo one, so are the disk routines it calls. Both would require patches
If you need someone to make tests on this, you can count on me.

Does the Orchestra-90 ROM include its own mini-DOS and access the disk controller directly, or how does it work?

[pser1]

right now I can't tell.
I am trying to dig in the unassembled code looking for std disc routines calls .
My problem is that, despite knowing how Dragon DOS is built, it seems that the CoCo Disc system
is absolutely another thing. It hasn't the indirect table $C008-$C02A with 17 functions there
so maybe I would better learn a bit about the CoCo DOS before going on.
In fact it will be tricky anyway because the Orchestra is loaded at $C000 and the DOS is too
but at another MPI slot (probably number 3), so first I need to find out code parts that change
of slot and maybe there I will find something interesting ... need more and more time

Maybe use another disk rom like Delta or SuperDOS?
