back again with some news ...
After some brainstorming with Stewart Orchard, we have got to reduce the 'needed areas' by the modified Orchestra90
so that now it can run without problems as a ROM, even in the Dragon 32 (no more need to switch to MAP1)
- You can burn the ROMs on a bank of a CoCo-SDC (from Ed Snider), see:
https://sites.google.com/site/thezippst ... s/coco-sdc
- If you have a Tandy MPI or a Y-Cable, you can also burn the ROMs into any of the banks of Roland Schweiger's (rolo) Multicartridge modules, see:
viewtopic.php?f=6&t=5366
- In case you don't have floppies and want to use tape to load/save scores, you can use Rolo's modules without the MPI / Y-cable too.
- If you dare soldering a bit (one or two wires), you could modify any floppy controller so that it can address 16k range and burn a 16k ROM.
The floppies will work nicely despite there is no DOS installed, of course only for the Orchestra program that contains its own mini-DOS.
You could say you have built your own Orchestra cartridge

If your machine has 64k and don't want to bother flashing or burning ROMs you can use the VDK that installs the ROMs into MAP1 without any further
requirements. Simply use this VDK file: "OR90V3R5 - Dragon - ROM with installer into MAP1.VDK"
Use program ORCDDAC.BAS to play via internal Dragon DAC
Use program ORCCART.BAS to play via the Orchestra Cartridge (MPI or Y-cable)
The ones that prefer to install it in the CoCo-SDC may use this file: "OR90V3R5 - D32 - ROMs - SDC-Updater (Both versions).VDK"
To install the version for the real Orchestra CARTRIDGE, you need to use the basic program: "INSCART.BAS"
If you want to install the version that uses the Dragon Internal DAC instead, then use the basic program: "INSOR90.BAS"
have a nice listening!
cheers
