Yes, one of the "special" file types was used.


The one which almost nothing uses...except LISA assembler, iirc?
Dunno. With the different representations in different DOSes, it's hard to recollect such tiny details. :-) 


The 2.9 I have says "11-0/R" instead of the expected "11 0 R".

2.8 is as you say.  Both have it on the bottom right.
3.0 has it with the dash and slash, in the TOP LEFT. (Which is odd... every other variant I've seen that shows the status does it in the bottom right.)
This is funny. I won't rule out some additional hack by another person for own customization. A binary compare will tell whether it's only a few bytes patchwork.
2.9 and 3.0 also beep around when I hit the keys. (Which is why I tend to prefer the 2.8 I dug off the disk image that comes with Appler.) 

This 2.9 I just booted is silent, i.e. normal.


I wonder if it was a common hack.


Not in my case.
They also seem to have ONERR TRY AGAIN built into them. (Nice feature, though I'm not exactly a fan.) 

Some BASIC additon? Mine doesn't have such.


It's a hack on the DOS, so that instead of say

]

FILE NOT FOUND

]_

it would instead do something like this:

]_

FILE NOT FOUND
The Beagle Bros version of this is called "ONERR TRY AGAIN" and I think it's on Silicon Salad. 

Ah, I see. It's there.
It was good practice to incorporate useful bits from here and there. For instance, the ROM of Pravetz-8C had nice additions like Ctrl+Reset+ClosedApple dropping you into Monitor (great for hacking), or supporting hex constants in the "$xxxx" form in BASIC. Also the more common mini-asm, Step/Trace and search in Monitor. Try it, image is available on the net.
It does look very different under the hood than most DOS hacks. More different, even, than DiversiDOS. 

It was the most differing but still compatible DOS as I remember it.
If you look at the hack I use on my disks, it's close enough that the vast majority of programs still work. (A notable exception was Terrapin Logo - a problem I traced to lobbing out the VERIFY command to make room for the TYPE code from ProntoDOS.)
Forgot that Eagle GraphExt also has "TYPE" command. But you probably have found that out already.
