Hi there,
I successfully emulated an apple II+ with my emulator. I threw the apple II+ Rom at it at it beeped and booted up correctly.
Now I wanted to test an apple //e Rom. It did not even boot and displayed nothing.
Do I have to take care of something if i want to do an //e emulation?

In article <63412775-fd79-411e...@googlegroups.com>,
The Apple //e adds INTXROM to map ROM at $C800-CFFF, and it's used during
boot. There are lots of new softswitches on a //e, especially for 128K
of memory, plus double-hires, etc. And depending on the ROM, it may
require slot 3 80 column card ROM mappings as well, requiring some aux
memory. And and enhanced //e has a 65c02 with lots of new instruction,
which will be used in that ROM.
