o.o?

I use emulator-assisted cracking so some things that might be difficult even with, say, an Apple IIgs, aren't as hard here.

What I did determine was that the entry was 0803. However, some code isn't executed that should be, which is vectored in from 0800. (Both copies I have go directly to the ? prompt. A copy I used on metal in 1990 had a message which I found when doing an 800G from the debugger.)

I'm guessing your "master or slave?" comment has to do with DOS relocation? That's not as much an issue here - I simply freeze the emulation and dump the entire contents of conventional memory. (Grabbing the language card memory is more difficult, and I usually go into dosbox and run ApplePC so I can use EDM to do a quick memory move, then boot a slave DOS disk and BSAVE, and pull out the file with Ciderpress.)

Terrapin Logo - one file plus a wedge that did a MAXFILES 1 before running it - is much simpler. xD Still takes 64K, though it latches on to the existing DOS. (It's also incompatible with the patched DOS I use...because of the free disk space patch from ProntoDOS.) But Apple Logo provided a bit of a dare.
