Hi Ken!
thanks for this recopilation (and recompilation too)
It is a great collection.

Hope to be able to make some tests tomorrow despite there is quite a lot to play with
I will let you know

cheers

Question for Ken maybe... I was looking to have a play customising some Nitros-OS9 builds for the Dragon. Thus far I've checked out the repro using HG and built the Dragon & CoCo1 disk images. They all build ok but whilst the coco1 creates "native", drivewire & becker-drivewire disk images, the D64 one only appears to create the "native" version. So I was wondering how you went about created the drivewire enabled versions since that would (probably) be my starting point.

Thanks,

Jon.

I used the CoCo2 build, with in port.mak to get the Dragon keyboard layout.
Hence the CoCo disk controller drivers.

Thanks Ken, I will have a play and see what I can break...

This is my hacked together build of a Drivewire enabled NitrosOS9 build for a D64 which pulls in the Dragon disk controller rather than the CoCo one. This is useful for transferring individual files (as opposed to making complete disk copies) from/to floppy disks and Drivewire. Thanks to Ken for pointing me in the right direction for his original ports.

Hi Jon,

I have tested this file today, it works great!
I can easily access my two floppies with /D0 and /D1
The only 'con' is that this disk was not thought to work extensively with it and so, it works in text mode ...
Besides, I have not found those old commands to change mode (go40, go51, go32)

My OS-9 / NitrOS-9 knowledge is sooo basic that I would need to read the whole programmer's manual
to be able to make the smallest mod in these kind of files ... sorry.

cheers

Hi Pere,

Not sure what you mean by:

I didn't bother enabling the 51 column display mode for this build because it didn't seem that important when my primary aim was to just copy disks and that 6K of RAM would be put to better use as a disk buffer...

From memory, those "go51" type commands are best avoided because the 6K of graphics memory it allocates effectively fragments the memory leaving not a lot of room left to do anything.

Rgs,

Jon.

Alright,
that explains why it works in mode 32.

cheers
