Hi,

I thought about a NitrOS-9 version for emulators that would accept both 
DNS=1 and DNS=3 for 2880 sector disks.

1. No one will want to support two versions.

2. The change will never appear in the nightly builds because they are not 
being built.

3. If they are built no one will use them. What's a nightly build, is it 
good to eat?

4. Of the people in the CoCo world, 1.5 are in sync.

5. There is no way to get everybody in sync.

6. Where are the Original OS-9 disks was asked so often that I created a 
thread. Eight Hundred Ninety Six views (896)

7. I got only one vote when I ran for dictator. Fine except no one else got 
any votes. I really wanted someone to run and accept being dictator.

8. When is the next release of NitrOS-9 to occur? When will a new NitrOS-9 
file for VCC to be released.

9. If this list is read backwards will it make it on Letterman?

10. I plan to die one day after Dave Lettermans last show.

11. Dave has said he will do one more show than Leno

Time for the Scottish comic to come on with his horse and robot.
