 Re: plus4emu 1.2.5

I can change the address parsing in future versions (I assume the 'c1551' would refer to the 1551 ROM, which is mapped to $080000-$083FFF, and the actual IEC devices would be like U8 etc. or similar, as there can be more than one drive of the same type) to have mnemonics for specific areas. However, as a simple rule, an address like $1nxxxx refers to the address space of device 'n', and the main CPU is assumed to be device 0 (so $18xxxx is floppy drive U8, $14xxxx is the printer / U4, etc.). The Plus/4 RAM is at $3Fxxxx if the size is 64K, and the basic and kernal ROMs can always be seen at $000000-$007FFF.
