Well, I dont know much about magic, but of course it is possible to burn
it into a rom. There maybe two small problems:
1. The Falcon-ROM ist 16bit chip with capacity of 4Mbits (or was it 8?)
   and most ROM-writers only support 8bit Chips. But at university there
   should be no problem in doing it :)
2. You will have to recode magic. The ROM must start with a complete
   bootup-seqeunce. You maybe have to add some stuff to reset and init
   hardware, but maybe it is already present, then must find thomething
   tst.w sys_ctl
   tst.w sys_ctl
   or something like this. The other thing is that magic surely has some
   data inside code, which is write by it. Of course ROM is read only, so
   you have to allocate this stuff in RAM.

Thats all

Bye Joerg
