Well, that's a clue for sure... do you only have 48k of memory in that II+ of yours?

Ok, it sounds like you have a good install running since it's able to manipulate the drives on startup. Do you have any idea if the drives actually work or not with other disks?

Does the disk drive get accessed when ADTPro starts up? It should be probing the disk drives available at that time.

Do you have a blank disk inserted in the disk drive when you go to format it? I can also imagine a scenario where you've loaded ADTPro on top of plain old DOS rather than following the bootstrapping steps from the very beginning - that could cause a situation where the program would run, but it wouldn't know how to operate your disk drive... i.e. http://adtpro.sourceforge.net/bootstrapaudio.html#Starting_from_bare_metal paying particular attention to step 2.

But the physics of the wings (lift, drag) change when inverted. One way of avoiding simulating that is to make it impossible to do.

That would negate the controls argument... can you maintain inverted flight?

I can't imagine the physics engine would/could take inversion into account.

My guess is the disks are fine... I'd be looking at the images that were copied to them before I suspected the disks. And, as others mentioned - I'd format them with a formatter utility and try writing/reading them.

Maybe you'd better post a picture. There's no sense in which a "dual floppy" could be connected to a Disk II adapter card...

Yes, you should have drive activity at startup. Take a close look at your Disk II card and the connection it makes with the ribbon cable. It should be connected to the upper header (marked "DRIVE 1") and all pins should be engaged. It is easy to be off by one row or one column, and that will have particularly disastrous results for the drive. Ensure the card is in a higher slot than anything else that might try to boot (i.e. the Slinky card). Slot 6 is generally the default for floppy drives.

Actual dictation/speech-to-text sorts of stuff didn't come until (much) more powerful processors came along.

Yep, they sure are all compatible with the IIe. Depending on the age/version of you IIe, one may be more period-correct. The first IIe machines typically had the old-style Disk II drives; the matching ones came a bit later.

Yep. I personally find that more practical to do on an OS9 Mac, but I'm lucky to have some bench space to keep a few "bridge" machines up and running.

...and software for same is even more hen's teeth-like. It's simply not practical. (Not that it matters, of course...)

I don't see the attraction, personally... the machine you plug these into has approximately zero software that comes on a 3-1/2" disk.

You had a carton of 3.5" controllers? That would indeed be a trick. Too bad you didn't hang on to them. They're perennial favorites when they come available, yes.

There's a new audio test capability built into this one: http://adtpro.sourceforge.net/connectionsaudio.html#Testing

Excellent news, that was the main goal for sure.

Does your manual actually use the word rom - as in romfile and rompath? I would expect it to say disk image or something like that. But I'm not able to get -d1 to work either. I wrote up a defect a few years ago that Tom fixed regarding a floppy disk parameter - but I can't remember what it was now, and of course Berlios (the old hosing service) is now gone too, so I can't really look it up. Edit: try this command line: applewin.exe -f disk.dsk (or whatever your disk image is called). You might have to hit F2 to boot it if your Windows isn't set up to automatically associated .dsk with AppleWin.

The text scroll demo and Cable demo run without trouble. I'm at the limit of what I can do; the stuff in the root prefix mostly doesn't work. Can you try a different emulator? Virtual ][, perhaps?

Did you upload another version? I can see SPLIT now. :-) But it seems it still has some modifiers in your BASIC.SYSTEM... PREFIX, for example, prints out the prefix and sets up the cursor to enter a new one. But it doesn't come up in 80 column mode... which makes STARTUP a little problematic.

I don't see a program called SPLIT... there's SPLIT.NOTES, SPLIT.HELP, and SPLIT.LOGO. Testing on GSport (I assumed you targeted a GS, since it's an 800k disk image... which would be very unusual for a plain Apple II) Startup seems to make some odd assumptions about the screen starting in 80 columns - the screen viewer look a little funky in 40. Boot the disk, hit 0 to quit, then run TEST.MAIN. Program says to hit Ctrl-A... do that, and you get SYNTAX ERROR IN 30. The same thing happens if you run TEST.AUX.

Ok, but... can you upload it somewhere so we can take a look? Now you've got our collective curiosity piqued.

Is it possible this is a variation on (or simply) Conway's Game of Life?
