Re: Official and LEGAL ways to emulate Apple II?

[jishcat@hotmail.com (Josiah Ong)]

One possibly legal solution, athough cumbersome, would be to construct
a small device that would actually transfer the contents of the actual
ROM to the PC (over a serial port perhaps) just before starting the
emulator.  The ROM image could then be removed when the emulator was
exited.  By doing it this way, you would kind of be using the actual
ROM.

This device could be made rather inexpensively using a PIC
microcontroller.  My guess would be about $20.00 each, maybe cheaper
with effort.  Actually, depending on how big the rom is, and how many
address lines, etc, one might be able to make a device that just
basically plugs into the parallel port, without any real electronics
on the device at all.  These would be really cheap.

If this method of copying the entire contents to the ROM to the PC,
and then deleting it when done is not completely legal still, then
another solution might still exist.  This would need to have the
reader be accessed byte by byte by the emulator, just as the real 6502
would access the real ROM.  I think this might just be possible on the
parallel port quickly enough.  The emulator would need to be modified
to support this, of course.  This should be completely legal, since
the emulator will not run without the device with the ROM chip in it.
