[Coco] The DOSes

[Stephen H. Fischer]

NO NO NO!!!!! 

DECB is what you get when you turn the CoCo on. 

DISK Extended Color Basic. An interpreted Basic at that. 

The Disk ROM Inside the controller does NOT make ECB an OS!!!!! 

I was an Super Computer, Programmer working on Operating Systems starting in 1967 and ECB just has some added disk access commands.

My experience with Operating Systems goes back to ~ 1965 when I was running a Computer that was not damaged when a huge bomb took out the lower three floors of the building. That Super Computer was not damaged as it was in crates ready to be shipped back. One year and a day earlier and I would have been toast. Bomb was early Monday morning, I worked Sat and Sun early mornings.

Where did the name RSDOS come from. Perhaps some people trying and failing to raise DECB to a level that is just incorrect.

Yes I know RSDOS is a folder on RTSI where all the good stuff is for both OS-9 and DECB.

Even OS-9 folks who have a real operating system made an mistake in that name.

But then the NitrOS-9 people have destroyed the user interface (Communally called a shell) with the very botched up ShellPlus. Not a good example now of an OS.

We built the computer a connecting logic together with a huge plug board.
My loader program via teletype punched paper tape using each character as an command was not a shell. 

Yes I am going to keep saying that until the end. I have too much experience to stop.
